INTRODUCTION                   |
-------------------------------

The Binding of Isaac is action/shooter dungeon crawler heavily influenced by
Legend of Zelda with roughe elements and pretty much everything you've ever
wanted in this style of game. Since The Binding of Isaac is heavily randomized,
it will be impossible to predict what you'll see or receive at any time in the
game, but I'll be doing my best to make navigating the unknown as easy as
possible.

A HUGE thanks to all the people at the Binding of Isaac wiki for providing
access to information that would have taken so much more to find.

The story of the Binding of Isaac is simple yet devious.
Isaac lives at home with his mother in a small house atop a small hill. Isaac's
mother spends her time obsessing in religious broadcast television paying
little or no mind to Isaac.
One day, Isaac's mother hears the voice of God. God informs her that Isaac has
become corrupted by sin and must be cleansed.
Isaac's mother takes from him all of his personal possessions; his toys, his
drawings, his clothes; and locks Isaac in his room.
But the voice of God is not satisfied, he requires a sacrifice of Isaac for his
mother to prove her devotion.
Determined not to fail God, Isaac's mother grabs a butchers knife and prepares
to kill her son.
Seeing his immenant doom approaching, Isaac searches desperately for a means of
escape.
Finding a trapdoor leading into the basement beneath the rug, Isaac plunges
into the depths just before his mother bursts through the door.
Cold and alone, Isaac's only choice is to delve deeper into the darkness,
facing his fears and insecurities and, ultimately, his mother.

CONTROLS                       |
-------------------------------

The Binding of Isaac utilizes the keyboard (or dual stick analog controllers if
you have one) in order to play. Alternate mouse/keyboard controls are also
available.
   _
 _|W|_
|A|S|D|\
\_\_\_\|  Basic Movement - Up, Down, Left and Right. Navigate the rooms to
your heart's content

   _
 _|^|_
|<|v|>|\
\_\_\_\| Attack - Sends a single tear flying in the chosen cardinal direction.
Hold for rapid fire (see "Tears" section of stats). The trajectory of your
tears adhere to Newton's laws, so tears will retain any velocity you had at the
time of firing; that is to say moving to the west while firing north will cause
the tear to move on a north-west trajectory; moving and firing in opposite
directions will slow tears and reduce range; moving and firing in the same
direction will speed up tears and increase range.

 _____
|SPACE|\
\______\| Use Item - If you possess an activatable item, pressing space will
activate it. See activated items.
 _         _____
|E|\      |SHIFT|\
\_\| OR  \______\| Drops a bomb at the player's feet if you have one. See
items for more info on bombs.

 _
|Q|\
\_\| Use Card/Pill - If you are currently carrying a Tarot Card or a Pill of
any kind, this will consume that item and produce an effect. See items for more
information on Tarot Cards and Pills.

SAVING - The Binding of Isaac DOES NOT have normal saving like some games. If
you die, it's game over and you'll have to try again, however the game DOES
have an autosave feature that tracks stats (such as items found/discovered and
achievements unlocked). Never quit the Binding of Isaac through any method
other than the "Exit Game" option on the main menu or you may lose some
progress.

BASIC WALKTHROUGH              |
-------------------------------
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Quick tip - If you see this, there is some general strategy or helpful info
provided. Even if you aren't planning on reading its particular section of the
walkthrough, take the time to read these as they often apply to later floors as
well!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
PART ONE - THE BASEMENT

Welcome to the basement, you've officially descended into what will either be
your salvation or your death depending on how your luck and skills pan out.
You will automatically start in an empty room with the game's controls
conveniently scrawled on the floor before you. Assuming this is your first
playthrough you should take note of you current HP and any bombs or cash you
may be starting with (depends on character).
Working under the assumption that you're playing with Isaac, you should have a
bomb to start with. DONT WASTE IT NOW.

!!!!!!!!!!!!!!!!!!!!!!!!
Bombs and keys can be dropped, bought and found in chests. You occasionally
start with one if your character includes it. In early levels you can go whole
floors without finding ANY of either so use them wisely.
!!!!!!!!!!!!!!!!!!!!!!!!

A word from the wise - This game is randomized quite a bit, the room layouts
and types will vary and the enemies and bosses spawning will as well. Nothing I
can do will tell you what will be in your dungeon besides what is not
randomized so from here on out it's strategy and assumption.

From this room there may be doors extending out into one to four other
directions.
Take a quick note of your HUD and menu options, get a handle on the shooting
controls and limber up. The more ready you are for the next room, the less
likely you'll get hurt. Don't get hurt.

On this floor, enemies will be relatively easy, ranging from flies that follow
you (red), flies that just buzz around (black), hopping corpses (minus a head
O_O), floating heads (minus a body o_o), zombies (sometimes without eyes x_x)
and all manner of horrible things which you can read about in the bestiary
later... or now if you want to skip ahead.

Rooms on this floor are typically the most basic types. From this point on
until any level past the depths 2, every floor will ALWAYS have the following
(including floor 1)
-A Treasure room (always locked except for basement 1)
-A Shop (always locked)
-A boss room (never locked)
-A "Secret" room (not on the map, blocked by a breakable wall that can be
opened with a bomb)

!!!!!!!!!!!!!!!!!!!!!!!!!
Floor 1 treasure rooms are never locked
!!!!!!!!!!!!!!!!!!!!!!!!!

Familiarize yourself with pills and Tarot cards if you'd like, otherwise use
this guide as a reference.

Rooms on the Basement 1 will typically contain either enemies, items, chests or
a combination thereof.
Any room with enemies will lock upon entry, after clearing, the room will
unlock and an item or chest MAY spawn in the center of the room.

Enemies on this floor will typically be pushovers with minimal AI. Some enemies
will not deal touch damage, though most of these enemies will spawn flies on
being killed, so expect the unexpected.

Explore the level as you can, leaving behind any items or chests that cannot be
reached without a key or bomb. Make your way to the treasure room, which will
have a golden crown on the map and a golden door on the screen. This room will
almost ALWAYS be your first destination on EVERY floor from here on out and you
should ALWAYS keep a key on hand for future treasure rooms.

This floor will typically have about 10 rooms to explore.

A quick monster guide to the basement:
-Flies (in all varieties)
-Gaper
-Horf
-Gusher
-Hopper
-Mulligan
-Mulligoon
-Clotty
-Moter
-Clot (not to be confused with Clotty) AKA Mini-Gish
-Embryo

!!!!!!!!!!!!!!!!!!!!
A Treasure room ALWAYS contains a free treasure which is either a Passive,
Activated, or Familiar/Orbital (See items)
!!!!!!!!!!!!!!!!!!!!

Speaking of keys...
If you find a key it has 3 primary uses:
Open Shops
Open golden chests
Open keystones

On floor one only the first is a guarantee and with little or no cash it's not
recommended.

!!!!!!!!!!!!!!!!!!!!!
Shops contain anything from hearts to treasures. Every item has a default price
and a sale price (which is approximately 50% off). As to which price an item
takes is random, but the base price for item types is static. If keys are
scarce, keep this in mind: A treasure in a shop will cost 15 coins, 7 if it's
on sale, so unless you are crossing your fingers for something else, entering a
shop with any less is usually a waste unless you are looking for Greed (see
Bosses)
!!!!!!!!!!!!!!!!!!!!!


This floor may also contain a mini-boss which will be announced by a fanfare
and sudden change in music. Mini-bosses are usually one of the Seven Deadly
Sins (see below) and should not be taken lightly early in the game. If you
encounter one, feel free to pause, run to this guide and be prepared to fight.
It helps to know a boss' moves and attacks.

Explore your current floor to its fullest, keeping in mind that somewhere a
secret room is hidden, though the likelihood of finding it is generally rather
slim at this point and may not always be worth the effort.

When you're ready, head on over to the boss room and see who the game sends
your way. Your first fight will most likely be with Monstro who can take a
beating but is easy to dodge.
Other possible bosses include Gemini, Larry Jr. and the Duke of Flies.
On a very rare occasion you might face the Fallen instead... if this happens
you should cross your fingers and steel yourself as he is of a much higher
difficulty level. On the bright side, if you do manage to defeat him the reward
is often well worth it!

After finishing off a boss you will always be rewarded with a treasure and a
trapdoor will appear in the room. At random, a second door will appear with a
gargoyle over it, this is the Devil's room. Consider entering if it appears,
but be sure to read the rooms section first!

Your second treasure (from the boss) will more than likely be a health or stat
boosting item. Claim your reward and delve deeper into the basement.

Before you leave, should you have any bombs or keys left, consider visiting the
shop, shearching for the secret room or obtaining any locked chests/blocked
items. Your minimap will conveniently list any left-behind items and chests, so
feel free to manage your inventory at this point.

!!!!!!!!!!!!!!!!!!
Dark-tinted rocks (blue-ish in shade) are not there for looks, they are
guaranteed to contain a random item (often soul hearts) when blown away by a
bomb
!!!!!!!!!!!!!!!!!!

From here things only get harder!

!!!!!!!!!!!!!!!!!!
After floor 1, all treasure rooms will be LOCKED, so keep a key handy to open it
!!!!!!!!!!!!!!!!!!

Floor 2 will typically offer more of the same as floor 1 with some added
difficulty, size, and slightly more to see than before. Just take this floor
one room at a time keeping on the defensive, no use wasting HP.

!!!!!!!!!!!!!!!!!!
In the event of you receiving 2 activated items (one from the first floor,
another on the second), now would be a good time to fully understand what each
one does. Prepare to leave one behind but feel free to use up the second one
before you part with it for good.
!!!!!!!!!!!!!!!!!!

This floor will typically have about 13 rooms to explore.
At this point you may encounter a room with bars. This is the arena. See the
rooms section!

As was the case in the previous floor, explore and grab your treasure if you
can. Keep safe and take on the boss at your leisure. Get a hold of the flow of
the game and work on hit and run tactics with any enemies that can spit blood
at you.

Your second boss fight will likely be either Monstro (if you did not kill him
previously), Gemini, the Duke of Flies or Larry Jr.
Claim the second boss' treasure and dive into the next section, the caves!

PART TWO - THE CAVES

!!!!!!!!!!!!!!!!!!
From here on in you may encounter Pits, Spikes and Explosive Barrels. See
dungeon features for more information.
!!!!!!!!!!!!!!!!!!

The caves are larger and more dangerous than the Basement, introducing more
enemies, bigger floors (resulting in a greater variety of rooms), stronger
bosses and harder to reach items.

In addition to the previous enemies you may also now encounter:
-Boom Fly
-Charger
-Host
-Hive
-Maw
-Maggot
-Spity
-Knight (rare)
-Leaper (also rare)
-Mr. Maw (also rare)

As with the Basement, prepare to play defensively and conserve your hearts.

The list of possible bosses for the Caves typically includes Peep, Chub,
Fistula or Gurdy. For the most part, none of them are that difficult if handled
properly.

Keep hunting down those treasures and start considering store purchases as you
will likely have plenty of money to spend at this point.

!!!!!!!!!!!!!!!!!!
Need more HP? If you encounter a blood bank/blood donation machine (see
rooms/dungeon features) consider donating some HP for cash. If you're lucky you
can score a Blood Bag which will boost your max HP.
!!!!!!!!!!!!!!!!!!

You may from this point forward encounter weakened bosses randomly instead of
normal enemies!

Keep safe, fight well and the basements should breeze by.

PART THREE - THE DEPTHS

If you've made it this far, you've either gotten lucky with the right treasure
combinations or have gotten the hang of the game. The Depths will offer more of
what the caves gave you plus more enemies than before including:
-"Baby"
-Boil
-Brain
-Guts
-Globin
-Knight
-Mr. Maw
-Leaper
-Vis
-Leech (rare)

Additionally, previous bosses may appear normally instead of enemies, including:
-Fistula (multiple parts but never the whole)
-Blastocyst (occasionally the smallest parts)
-Chub
-Larry Jr.

In addition to all the dangers of the previous floors, the Depths may also
include Statues which will spit blood at the player until the room is
completed. These CANNOT be moved or destroyed AT ALL.

Door blocks will now occasionally appear, blocking access to chests or features.

Your first floor boss here will either be Loki, Monstro II or a previous boss
at a higher difficulty level.

!!!!!!!!!!!!!!!!!
As you progress, hearts and healing items will become rarer, treasure chest
contents will be less useful, enemies will be stronger and often the random
elements of the game will flat out start trying to kill you. Be conservative at
this point, it doesn't hurt to be overprepared.
!!!!!!!!!!!!!!!!!!

The final level of the Depths will mark the closure of your first adventure.
This floor will contain your last shop and treasure room, so be sure to visit
both. If you have money to spend, buy what treasures you can. Prepare for the
boss and ensure you've done everything you need BEFORE entering the boss room
(especially if this is NOT your first play through) as after finishing this
boss you will NOT be allowed to re-enter the depths.

*********POSSIBLE SPOILERS BELOW*****************

The boss here is Mom, check her up in the boss section and be ready for one
crazy fight.

After finishing Mom, you will have beaten the Binding of Isaac if an ONLY if
this is your first time playing it, otherwise you will be given another
trapdoor and be sent on your way to...

*********POSSIBLE SPOILERS BELOW*****************

PART FOUR: THE WOMB

If you thought the previous floors were hard and or creepy, then you're in for
one crazy surprise because the womb is harder and creepier than before. Bosses
are more common in random rooms, all damage is increased to one heart damage.
Additionally, there are no treasure rooms (save for the possibility of a
treasure in the secret room), no shops and definitely nothing "easy".

!!!!!!!!!!!!!!
NOTE: From here on in, Blood Donation Machines will consume ONE FULL HEART
instead of half a heart. Be extremely cautious if seeking a blood bag.
!!!!!!!!!!!!!!
The monster list now includes:
-Fred
-Leech
-Lump
-Pokies
-Para-Bites
-Membrain
-Dople
-Eye

as well as most of the previous bosses fought including:
-Larry Jr. (in various quantity/length)
-Monstro (in various size/quantity)
-Gemini (sometimes 2)
-The Duke of Flies (rare, sometimes 2)
-Blastocyst (all but the largest, sometimes up to 5)
-Chub (sometimes with other bosses)
-Fistula (including the full boss)
-Loki
-Peep

There usually isn't much of a reason to stick around and explore unless you
need to charge up your activated items or are hoping for a random treasure out
of a chest or mini-boss should you find one.

The boss on the first floor here will either be Blastocyst (in his full form)
or Scolex. Neither is too difficult and you can always go back after beating it.

By this time you should be making your final preparations for the final floor
of the womb. These rooms will only get harder, the fights more intense and
naturally this is all leading up to an epic battle against...

*********POSSIBLE SPOILERS BELOW*****************

Mom's Heart! As with the fight with Mom, you will not be able to leave
afterwards, especially if this is your first time fighting it.

Assuming you beat Mom's Heart (easier than it sounds) you will be offered a
giant golden chest. Open it to claim your reward, but be aware that if you
finished with enough HP or have properly unlocked Sheol, you may receive a
Devil's Room in addition to the Chest. In the Devil's Room you will find a
trapdoor leading deeper still... this time to Sheol. Passing up the chest for a
shot at Sheol will NOT cause you to lose your reward OR the resulting ending
clip, both will be unlocked automatically if you choose to go deeper and will
be waiting for you upon your resulting success or failure. NOTE: if you manage
to complete Sheol BEFORE properly unlocking it, it will count DOUBLE towards
your completion count (meaning you will get an extra unlock!)

*********POSSIBLE SPOILERS BELOW*****************
PART FIVE: SHEOL

This area was added with an update to the Binding of Isaac and features your
greatest test of courage and strength. Here you will find NO help save for a
possible single arena and a definite secret room. Bosses and mini-bosses in
duplicate forms, with additional enemies and in all varieties can be found here
instead of normal enemies and rewards are virtually nonexistant. Avoid getting
hurt at all costs and be prepared to keep a full healing item on hand if you're
lucky enough to find one. Hearts are scarce and damage is high, nearly all
normal enemies will be improved "champion" varieties (see monsters section).
Additionally the following enemies will also appear:
-Dark Dople
-Evil Eye
-Exploding Leeches

The boss here will ALWAYS be Satan. Defeat him and obtain your ultimate reward
and the final mysterious ending.

BOSS LIST                      |
-------------------------------

In the Binding of Isaac, bosses fall into a few basic categories:
Normal Boss - Occurs in a boss room at the end of every floor
Mini-Boss - Appears in a mini-boss room, randomly found in floors, shops or
secret rooms.
Champion/Enhanced/Alternate Boss - Replaces a normal boss randomly
Random Encounter - A boss may appear with or in lieu of enemies in a room in
any floor in the Caves or Deeper. Includes most normal, mini and champion
bosses.
************
The Basement:
************
#Monstro# - A large head with a cleft pallet.
Attacks:
Spews a wave of blood, easy to dodge, often miss. Large shots deal 1 heart
damage, small shots deal 1/2.
Jumps around attempting to hit the player for 1/2 heart damage.
Jumps into the air off screen, crashing down and sending blood flying out in
all directions. 1/2 Heart damage, 1 if hit by large shots.

Alterate forms:
Dark/Grey - Increased size and HP, cannot leap off screen

Red - Smaller size, reduced HP, appears in pairs.

Strategy: Monstro, in terms of bosses in the Basement is difficult for a first
boss, especially if this is your first time playing, though overall he's a
pushover if you know what you're doing.
Monstro's attacks are all weak and rarely hit you, but he's a tank, so you'll
have to weigh either a very long or slightly dangerous fight. Your best bet is
to circle him and attack constantly, backing off only when he pauses for an
attack that he will telegraph with plenty of time to avoid. Just play it safe
and he will die, eventually.

#Larry Jr.# - A long, segmented work
Attacks:
Randomly moves around the room, rarely directly attacks the player,
occasionally drops piles of poop blocking your movement.

Alternate Forms:
Green - Reduced HP, can randomly fire blood shots in whatever direction it is
facing for 1/2 heart of damage, easy to dodge.

Blue - Increased HP, larger in size. Will not leave behind poop. He will not
split until he is at low HP. Drops a soul heart when killed.

Strategy: Larry is one of the most common bosses in the game, and is one of the
easiest too. Just keep a distance and take them out one at a time. Larry will
typically spawn with 2 or 3 bodies, each one at a random length. As Larry
weakens, segments will be destroyed and he will be "cut" shorter. A push-over
and easy to avoid and defeat.

#The Duke of Flies# - A large floating head stuffed with flies.
Attacks: Coughs up flies and attack flies, as well as special Large Attack
flies that deal 1 heart of damage.
Can deal contact damage while floating around.
When the number of flies around the Duke reaches its max, he will send the
flies flying towards you with a big push.

Alternate Forms:
Blue - Faster movement

Orange - Faster, spawns attack flies and suckers instead of normal flies and
attack flies.

Green - Spawns Moters instead of normal flies, coughs up a ring of blood every
so often.

Strategy - The Duke is pretty easy as a whole, but can get out of control if
managed wrong. Keep his flies in check, taking out only the ones that attack
you directly. Timing your shots can bypass his fly defenses. Overall he has
incredibly low HP and can sometimes be instantly killed with a bomb if used
properly (practice required). Just play it safe and he'll be easy, if you see
an opening in his defenses, circle around it and focus there.

#Gemini# - A pair of conjoined twins, connected by an umbilical
Gemini is actually 2 seperate bosses, always found together in one battle.
Sometimes one or both can be champion/alt colored.
Gemini Sr. - Will follow you around the room, occasionally charges at you at
high speed after which point he will stop to catch his breath.
Gemini Jr. - Attached to Gemini Sr., will regularly spit blood at Isaac until
he is disconnected or his brother is killed, at which point he will turn red
and fly towards the player to hit them (and will stop spitting)

Alternate Forms:
Blue - unknown effects, +Max HP?

Green - May start the battle detached, Jr. will only become enraged when Sr. is
killed

#Famine# - See the Riders Section

#Steven# - A black Gemini
Unlocked by completing the Basement (chapter 1) 25 times

Very similar to Gemini, though the tether between the two is tiny, so the two
appear to be stuck to each other (a reference to a game by Edmund McMillan,
"Time Fcuk")
Little Steven attacks more frequently.
Boss AI is much more aggressive.
When the boss is reduced to 2/3 of its max HP, Little Steven will seperate and
attack directly instead of spitting blood.
When either Steven is killed, he will explode into a spray of blood in all
directions at high speed.

Steven, despite seeming easy, is far more difficult in that he can be hard to
predict at times. If possible, focus on one Steven at a time, though their
close proximity makes this very difficult. You will more than likely be faced
with both Stevens attacking you, which always results in getting hurt one way
or another. Expect the blood spray when one dies and be ready to get hit or
dodge. Keep your distance and always leave an avenue of escape should Steven
get too close.

Always drops either "Little Steve" or "Steven" items. Unlocks "Little Steve"
when killed.

*********
The Caves:
*********

#Chub#
An enlarged charger, he looks like a massive segmented worm.
Chub, out of all of the bosses in the caves, is probably the easiest. Though he
has a decent amount of HP, Chub is easy to dodge and eady to manage as he's
fairly predictable.
Chub has two basic attacks:
Charge; he will open wide and come dashing towards you. While Chub can slightly
adjust his path on the way, as long as you keep a fair distance from him this
shouldn't be a problem. Furthermore, you can use this to your advantage in two
ways. One, his charge will also hurt enemies in the room, so allow him to
gobble up anything you don't feel like killing yourself. Second, his charge
will also consume any lit bombs in his path. Doing so will stop him and after a
brief pause the bomb will detonate in his stomach dealing normal bomb damage
(also to you if you're too close). As a last resort this not only stops his
charge, but hurts him AND makes him vulnerable to any other bombs you may
decide to lay next to him.
Spawn: Chub can stop and spawn enemies from his backside (yuck). Depending on
Chub's color/variation he can spawn smaller chargers usually to a maximum of
about 3 total in the room. Feel free to let him spawn to the max as this will
cause any future spawning attempts to simply do nothing, leaving Chub
vulnerable.

So as for strategy, just lead him around the room, taunt him into attacking and
just play things safe. He should be pretty easy to take care of.

Alternates:
Blue: Chub is slower but bulkier. Additionally he will spawn special Boils
instead of chargers. Deal with the boils first as they can become very
dangerous and difficult to dodge!

Green: Chub will spawn Spitties instead of chargers and will always spawn 2 at
once. There will be a max of 3 Spitties at any one time.

Orange: Chub gets smaller, maybe a bit weaker, but gets a noteable speed boost
and a more erratic AI so he's a lot more difficult to dodge or deal with
otherwise.

"Fixed": This will never appear as a normal boss, though in certain situations
Chub will spawn without his final segment. In these situations he will never
spawn any enemies at all.

#Fistula#
A giant ball of flesh and tumor and who knows what else. This monstrosity
floats around the room much like Envy, bouncing off walls and pits for some
reason. This thing has no real attack and will never attack you directly,
though he can become dangerous if you let him get out of hand.
Hurt Fistula enough and he will split into 4 medium parts, each of which will
also split into 2 small parts when hurt enough. As a result Fistula gets faster
and can have up to 8 parts at once. Individual parts can be found in rooms as
early as the Caves.
After killing a small Fistula, the part destroyed will immediately spawn a
Charger which can attack you. Chargers can sometimes take more punishment than
Fistula itself so be careful!

Alternate form:
Dark-Fistula: Darker colored and usually a bit bigger in size. This version
will initially split into 3 instead of 4 making a maximum of 6 total parts at
the end. Each destroyed part will release a Boom Fly or Bloat Fly instead.

#Peep#
Everyone's favorite piss-spraying blob of... disgust. Peep is one of the more
difficult bosses in the caves and can often cause a bit of pain if not taken
seriously or carefully!
Peep slides around and attacks occasionally;
His normal attacks include releasing a puddle of urine which hurts you if you
walk over it for a full heart of damage.
Peep is also able to hop up slightly and, upon landing, will spray out a dense
circle of piss balls, each of which does 1/2 heart of damage.
Finally, Peep can jump off screen Monstro-style and will land wherever the
player was when the attack starts tracking you, so he shouldn't land on you if
you move. Landing will cause him to release another circle spray of urine at
you.
When Peep reaches 66% and 33% HP he will lose one of his eyes which will go
floating out and will now bounce off walls in a bishop-pattern. These will do
touch damage.

Dealing with Peep isn't too hard, but avoiding getting hurt is. His circle
spray is fairly common and will require the player to back off to dodge, so
keeping a constant distance from Peep always helps. Use the room's natural
cover (if there is any) to help avoid attacks and remember that touching his
piss puddle hurts you more than anything else. Once he loses an eye or two keep
in mind that they will block your shots AND hurt you if they get in your way,
so make dodging them your first priority and take your time while playing
things safe.

Alternate forms:
Green: Peep will lose both eyes right off the bat! Now you get to fight this
guy while dodging 24/7.

Yellow: Peep will constantly leave behind a trail of piss that will hurt you,
even while he is jumping around though he is physically smaller in size.

#Gurdy#
By far one of the harder bosses in the game, and definitely one of my least
favorite. Gurdy is a massive pile of flesh and fat and who knows what else...
with a face. Gurdy stays stationary in the center of the room and typically
starts the battle with a pair of Boils and some flies in the room.
Being immobile, Gurdy makes use of a larger variety of attacks and abilities:
Blood wave: Gurdy will crawl into her body mass and pop out on either the front
or side (depending on where the player is), then immediately spew out a 5-part
spray of blood balls which become rather difficult to dodge.
Spawn flies: Gurdy will spew out attack flies behind her. After some time they
will move towards you.
Spawn Pooters: Gurdy will raise her arm and release a pooter from her armpit!
Spawn boils: Gurdy raises both arms and spawns a pair of boils in front of her.

Gurdy has a ton of HP and takes the longest to kill. All you need to know to
kill her is that you must remain diligent at all times! Kill the boils first
and make them your priotity if they appear. Ignore her other summons if
necessary and never stop shooting. When in danger, laying bombs in front of her
will speed the battle along.

Alternate:
Dark-Gurdy - Bigger, stronger, more HP... she can't spew blood anymore but
spawns far more frequently. Perhaps this version of Gurdy is slightly easier
than normal. Why? Well in this form she still has her spawn limits and the
player can camp the far side of the room and go largely unharmed through the
whole fight. Just don't fall asleep.

#Pestilence#
See Riders section

#C.H.A.D.#
C.H.A.D. is a living blob of blood and clots, and an unusually happy one to
boot.
C.H.A.D. behaves identically to Chub with a few primary differences:
C.H.A.D. spawns suckers instead of chargers.
He will shrink in size as you hurt him and increase in speed.

C.H.A.D. always drops Little C.H.A.D. when defeated. For an easy fight you get
an ok reward, though he becomes largely useless when you get enough soul hearts.

**********
The Depths:
**********

#Loki#

Another rare boss, you'll typically see Monstro II more often than Loki until
you reach chapter 5 where he *might* appear in doubles.
Normally, Loki is a little red imp who floats about and attacks randomly. Loki
mirrors chaos perfectly in that, at any time there is a lot going on with him.
Loki's room will hav a single floating poky in the room which will be cause for
some wariness on your part. Keep an eye on it.
Loki himself can either:
Teleport elsewhere in the room.
Send an 8 way attack of blood balls at you.
Launch a 4 way + pattern, then a 4 way X pattern then another 4 way + pattern
Or summon a Boom or Bloat fly, which, if a Boom fly, can be used to hurt him
back.

Knowing what Loki will do in advance is impossible, but knowing what he can do
helps. Simply deal with each individual attack one step at a time and you can
finish this battle unscathed.

#Monstro II#

Monstro's back with some improvements this time! Probably one of the easiest
bosses in the game if handled correctly.
Monstro II has a few simple upgrades from Monstro:
His bloody spray us now a blood beam that triggers if the player is in a
horizontal line from Monstro II
Monstro II will always super jump twice consecutively, each time either firing
an 8 way pattern of large blood balls or spawning 4 suckers.

Killing Monstro II the easy way!
Simply stand directly across from the beast and let him prepare his blood beam
which he will telegraph with a smile. When he does, strafe in a semicricle
around him attacking on the way and stopping directly in range of his blood
beam, BEHIND him. If done properly, Monstro will turn around and prepare to
roast you with another blood beam. Lather, rinse and repeat and you can come
through without even a scratch. Should he instead decide to super jump, just
dodge, kill any enemies spawned and get back to provoking him again.

Overall Monstro II is rather rare since there is only one boss in the Depths
besides the guaranteed one (see below) and his alternates are even rarer.
For the most part, one form will cause him to spawn less but move more, another
will make him more buff overall, though the same strategy applies either way.

#War#
See the riders section

#Mom#

It's time to face your fears and confront MOM!!!
Now is your first real milestone, and completing this boss will unlock the rest
of the game.

Mom's room is special, it has randomly scattered rocks and 4 boss room doors in
each of the cardinal directions.
The fight begins with Mom's Foot crashing down in an attempt to crush you,
dodge this.
From here on out, Mom has 4 parts/forms that will appear randomly all at once.

Mom's Foot: Will occasionally track you (a shadow will appear) and stomp down
on the ground, creating a bomb explosion, destroying rocks, enemies and
anything else in its wake.

Mom's Eye: Pops out of a door, it is defenseless so attack it to hurt Mom more!

Mom's Flesh: Pops out of a random door, spawns an enemy to defend itself and
eventually disappears. Hurt it like Mom's eye, but keep a tab on the enemies it
spawns, you'll need to take them out to keep alive.

Mom's Hand: If you stand too close to a door, open or closed, Mom's hand may
quickly pop out to smack you. Keep a distance from the doors to avoid this!

To make this battle predictable would be impossible, but to make it easier is.
For starters, Mom will telegraph her foot stomp with a grunt, so let the foot
land where it will do some good, such as on rocks or enemies. As for whatever
the flesh spawns, know that there is a total spawn limit, but you'll want to
control anything that will shoot at or chase after you, ESPECIALLY Globins.
When an eye appears, attack it. When the leg appears, attack it. When a peice
of flesh is exposed, attack it. Don't miss any easy opportunities and be
careful if you can. If this is your first time, be more concerned with making
sure Mom dies before you do, if you have unlocked the ability to go deeper, try
and preserve your hearts if possible.

#Gish#

Gish is a replacement for Monstro II once unlocked. He resembles a massive
black glob of tar and fights accordingly.
Gish behaves identically to Monstro/Monstro II.
He spews out a black tar bomb that explodes on impact. This leaves behind a
trail of tar that slows you if you walk through it (thats all the tar does,
it's safe to touch)
Gish's super leap is identical to Monstro II, being two leaps successively. The
first one does nothing, the second will spawn two Mini-Gish enemies.

Otherwise, Gish is probably almost as easy as Monstro II save for the fact that
the Mini Gish enemies spawned can occasionally be a hassle and his AI is not as
easy to manipulate, but he's rather harmless for the most part.
Killing him nets you the Little Gish familiar.

********************
Chapter 4 - The Womb:
********************

#Scolex#
Scolex is the weakest boss in the Binding of Isaac. He has the least HP of any
boss and can sometimes be instakilled if hit with a bomb or a powerful attack.
Scolex is a large tapeworm and has a weakspot on his tail. Hitting him
elsewhere will do nothing.
Scolex will leap in and out of the room a few times, after which point he will
either stick out his head or tail (ATTACK!) and then dive back in again. His
head will spew out three blood bombs that will explode on contact with the
ground, his tail will spew a random cloud of blood balls.

Just hit his tail with good timing and you'll be done in no time at all!

#Blastocyst#
Blastocyst, unlick Scolex, can actually be hard at times.
This fellow is a single "Embryo" enemy (you'll have seen a few of them by now
at this point) within a blob of jelly.
He will bounce around a lot, spraying random bits of blood around and
occasionally will fire out an 8 way pattern of blood.
Killing him will cause him to split into 2 medium parts which will no longer
spray blood but can still fire 4 way X or + patterns of blood. Each of these
will split into 2 small parts when hurt, which can now only spray + patterns of
blood.
Finally, killing the smallest part yields a single embryo which can do...
nothing. Just kill it.

To deal with this uncommon fellow, just break him down to his second form as
quick as possible, then again into his third form. Doing so eliminates his
ability to attack diagonally which makes dodging all the easier. If you only
manage one at a time, the remaining half can still attack on diagonals so your
ability to work out a safe spot in the room is hampered a bit. If there are 4
small versions, however, you typically can work out an area in which you can
predict who will attack where and dodge accordingly, leaving that nice little
safe haven, often in the middle of the room, where you can catch your breath
and pick them off one by one.

#Death#
See the riders section

#Mom's Heart#

This is it! Another major milestone for you and Isaac!
Mom's Heart, unlike Mom herself, is a stationary boss. Killing it is likely
EASIER than killing Mom at times. At the start of the battle, Mom's Heart will
be flanked by two eyes. Take these out first. No exceptions.
Mom's Heart has a predictable behavior: If there are enemies with it, the Heart
will rise offscreen and hide. If there are no more enemies with the Heart, the
Heart will descend and summon more. After a few seconds, the heart will rise
away again.
Once all of the enemies spawned are killed, the Heart will return and summon
more. This can continue forever if you don't focus on the Heart while it is
vulnerable. When the Heart is down, concentrate on it! Hurt it as much as you
can, THEN kill its minions.
Once the Heart is down to about 33% of it's HP, Mom will scream out Isaac's
name erratically (you'll know it when you hear it) and from this point forward
the battle gets a bit more intense. Instead of hiding, the Heart will now stay
down and summon enemies, all the while sending blood bombs flying in random
directions, exploding and leaving blood pools. These can hurt enemies too, but
don't count on it. Just kill the Heart as quickly as possible to avoid getting
too hurt.

At this point, you shouldn't need too much more advice, just kill the heart and
if you have all your heart containers full, be ready to have the chance to go
deeper!

#It Lives!#
Once unlocked (after beating the Heart/Satan a cumulative total of 9 times) you
will unlock It Lives! It Lives will now ALWAYS replace Mom's Heart and simply
ups the difficulty by spawning bosses instead of normal enemies.
The only difference between Mom's Heart and It Lives is the difficulty of the
enemies (bosses and knights and such) which get spawned. Otherwise, the only
difference is aesthetic and that much I won't spoil for you.

*****************
Chapter 5 - Sheol:
*****************

#Satan#

This is it! The final battle! Satan is ready to punish Isaac for his sins and
boy is he going to put up a fight.
This battle consists of 3 phases and I highly recommend you stock up on HP
before you fight him if possible. Lastly, if by some rare chance you're
carrying the Bible item, use it BEFORE even entering the room as using it in
front of Satan at ANY time will instantly kill you.

Part 1:
Satan will summon the Fallen flanked by two exploding leeches. Focus on the
leeches first as they can hurt the Fallen if detonated properly. A well timed
bomb before these minions appear can wipe out both leeches and put a dent in
the Fallen though this is difficult to pull off.
See the Fallen's section for more info on him, there's no other twist here
besides the 2 leeches and the natural Full Heart damage pentalty in the level.

Part 2:
Clearing out Satan's minions will cause the fallen angel himself to face Isaac.
Satan will rise from his pedastal and transform into a massive demon.
Satan's first form will hug the back wall and will travel back and forth with
no real pattern. He will frequently cough up two consecutive fans of large
blood balls, which obviously do 1 damage each. The fans will always be pointed
directly at you and are densest when first fired. Strafing is always an option
but Satan has a problem with that too. Passing in front of Satan may trigger a
very quick attack in which he will either spew a blood beam from his mouth or
fire two beams from his hands (leaving room in the middle). Thr reaction time
required to dodge either attack is VERY quick so avoid passing in front of
Satan and additionally try not to stop there when doing so!
This battle doesn't change at all for the entire duration, so play things safe
and chip his HP to 0.

Part 3:
When Satan his 0 HP he will fall to the ground, but the get back up and leap
offscreen, laughing.
Now comes the most chaotic part. Play this by ear and avoid getting hurt too
much, but balance this with the fact that you want to get done ASAP!
This is the VERY end so be prepared to come within an inch of your life.
In this new form Satan, from his invisible perch above, will send his massive
feet crushing down on you in an attempt to crush you just like in your battle
with Mom. The feet will display a shadow before falling, will land and release
an explosion (splash damage will happen!). The legs will come crashing down one
after the other, raising up to come crashing down again. All the while, Satan
will constantly summon Exploding Leeches (up to 2 at a time) which can cause
plenty of trouble if you aren't careful since you usually don't see them spawn.
I cannot tell you what weapons you'll have, nor how you should approach this
battle (offensive or defensive) but at this point use your best judgement and
remember, at this point you either win or lose.

***************************
The Riders and other Bosses:
***************************

@Famine@
Famine is the starved out horseman of the Basement. He can replace any boss in
the basement once unlocked.
Like all riders, he has 2 phases and in each phase has different attacks.
In his normal form, Famine will either spawn pooters (up to 2 at a time) or, if
the player is within his direct horizontal line of sight, he will telegraph a
charge attack where he will charge at you, head offscreen and return on the
opposite side.

His second form will cause Famine to but cut down to only his head, at which
point he will float lazily around and cough up fans of 3 blood balls
periodically, aimed at the player.

General strategy: In his first form, Famine is easiest in that you can provoke
him to attack by charging, which will destroy any pooters he hits and will also
prevent him from spawning more pooters in the meanwhile. Keep him charging and
you can chip him down to his second form without a scratch! In his second form,
do whatever you want, just avoid getting hit when he does attack (which gives
you reasonable time to dodge).
Your reward is your first Cube of Meat.

#Pestilence#
Pestilence is the rider of the caves. He will float around on his horse and
summon chargers and spitties below him. Pestilence leaves a trail of sickly
slime which will hurt you if touched. His final attack is a ball of goo which
he lobs at you and which explodes on contact with the ground, leaving more
slime and hurting anything in its blast radius (enemies included, though not
the rider himself).

When he is hurt enough, he will lose his head, at which point his horse will
cough up flies and he will continue firing goo balls at you.

Not too difficult really, a relaxing break in comparison to, say, Gurdy.
Pestilence can be dealt with by simply ignoring the enemies he spawns and
instead paying more attention to his goo trails and lobbed goo grenades. Allow
Pestilence to take care of his own minions! When his head comes off, he's
nearly dead, though the flies that get coughed up can annoyingly block your
shots. At this point you shouldn't have any difficulty claiming your next cube
of meat.

$War$
War is the rider of the Depths
While War is rather hard to encounter, he is not too hard to fight, though most
certainly isn't as easy as Monstro II.
War's normal attacks are generally harder to dodge, though taking him to his
second form will eliminate all of that danger.
On his horse, War can:
Fire a circular spray of fast moving blood balls (hard to dodge!)
Fly into the air offscreen and release 6 troll bombs throughout the room
When provoked into a charge, War will attack horizontally once, then again
about 1/2 a room lower and again 1/2 a room lower until he finally returns to
his original starting position (the result is 3 consecutive nonstop charges
from the top to the middle to the bottom, or the middle to the bottom to the
top or the bottom to the top to the middle depending on where he starts).

When War takes enough damage, he will lose his horse and chase you Lust style,
in which form he is a pushover. Hurting him enough will trip him briefly.

Not too hard, just watch out for his charges and definitely be prepared for an
unexpected attack.
Killing him nets another Cube of Meat

%Death%
The final rider! Death appears in Chaper 4: the Womb!
Death can summon scythes to attack you from across the room, either in a pair,
which will track you, or a quartet which will travel across the room. These can
be shot down if needed. Additionally, Death may unleash his Hourglass which
will slow you and your attacks down, making dodging tougher.
Once wounded to about 50% HP, Death will dismount his horse which will enter a
charging pattern like War, but will continue nonstop until destroyed (necessary
to finish the battle!)
Death will now summon knights in pairs (and occasionally knightmares in the
place of a knight) which will behave normally once summoned. Taking out Death
or his horse will still leave the other to deal with.

To fight off Death, try to simply avoid his scythes, attacking only those that
will hurt you and focusing more on Death himself. Chopping him down to his
final form will force you to take out both him and his horse individually, so I
recommend you focus on Death first. His charing horse can and will hurt knights
spawned in the meantime, so just pay attention to where enemies are moving.
Killing Death and his knights only leaves the horse which will continue
charging until you kill it. It has a bit of HP so don't underestimate it.
Death will present you with your final cube of meat.

*The Headless Horseman*
The Headless Horseman is a special boss, like the Fallen and can replace ANY
rider when one is encountered (the Rider will be rolled for first when you
enter the boss room, and if a rider is to be fought then the game will roll
again to see if the rider is replaced).
This means the HH can appear in the Basement 1!
Unlike the riders, HH has both forms at once and is actually a fight against
two bosses at once (both parts can be found in Sheol when you get there,
sometimes in multiples!)

The body behaves a lot like the second form of Pestilence, coughing up blood
balls that leave behind damaging pools of blood.
The head behaves like a cross between War and Famine and will float around,
coughing up a fan of 3 blood balls, as well as occasionally performing War's
3-run charge.

I recommend taking out the body first if you can, especially if the head is
busy charging. Killing the body prevents the room from getting bogged down with
blood. Once he's out, kill the head, watching out for the blood he spews at you.
Killing the HH will either yield "a Pony" or sometimes a normal Cube of Meat.
The Pony is well worth the dangers if you get it early!

/The Fallen\

This dark angel can appear in any boss room on ANY floor and in the basement,
like the Headless Horseman, can be a game ender easily!
The Fallen flies around the room and will spit two successive fans of blood
balls (first 3 then 4). The Fallen will also occasionally stop firing and
charge at you like Gemini, after which point, instead of taking a breather, he
will stop and release a + pattern of blood beams.

At 50% HP the Fallen gets tougher as he splits into 2 smaller versions of
himself who behave identically. Take them out one at a time if possible.
Circle strafing is recommended for this guy, but his blood beam attack will
force the player to take cover in a safe place.

This tough fellow will always reward an item from the Devil's Room list, for
FREE! Rerolling this item will always yield another Devils room item as well.
Worth the trouble if you can survive.

+Krampus+
Krampus randomly appears in the Devil's Room upon entering INSTEAD of Satan
with two special sales.
At first glance, Krampus behaves identically to the Fallen with a few minor
changes:
Krampus fires an extra blood ball per fan attack.
Krampus will never chase you, nor will he split when hurt.
Standing in a straight line with Krampus may prompt him to fire off a + pattern
of blood beams.

Dealing with Krampus is a bit more difficult than the Fallen in some ways in
that his particular form of attacks is designed to prevent you from circle
strafing. That being the case, you can still circle him, but doing so will
require more care, as damage from the blood beams can take you down if you are
too careless.

Killing Krampus yields the Lump of Coal! This item will make fighting quite a
bit easier for the battles to come.

**********************************
Mini Bosses, the Seven Deadly Sins:
**********************************
These appear in mini-boss rooms which are normally unmarked on the map until
entered. Having the compass or spelunker helm will identify them.

!Envy!
Probably the most annoying of the sins, especially if encountered in pairs in
later areas. His rewards are scant and his risk of hurting you is high.
Envy floats around the room like a Blast fly/Fistula. Dealing enough damage
will cause him to split into 2 copies of his head. Killing those will spawn 2
medium heads each. Each of those will spawn 2 miniature heads each when killed.
Each successive head size moves faster and is harder to hit making the room
rather chaotic if you don't focus well enough.
Killing Envy will reward a Troll Bomb, or if you're lucky, Shoop-da-Whoop.

@Pride@
One of the easier sins, he will walk around randomly and either attack by
raging and shooting strange lasers in each of the 4 diagonals. At other times,
he will jump up, put on his Troll Face, and drop 6 troll bombs in random
locations in the room. Pay close attention to the bombs and keep out of his
range/attack spread and he will die pretty fast.
Rewards a Troll Bomb, Tarot Card or the Anarchist's Cookbook

#Wrath#
Pretty easy, though he can be painful, Wrath is a carbon copy of Bomberman in
many ways. He will send bombs sliding at you which will eventually explode and
hurt whatever is in his path. Wrath's room is always a specially designed room
with a Bomberman grid and randomly placed rocks.
Wrath can only do blast and touch damage, plus his own bombs can hurt him.
Since touching his bombs doesn't use you, you can push or launch them back.
Killing him will reward bombs, troll bombs, Mr. Boom, or Mr. Mega.
NOTE: Having Bobby-Bomb will make Wrath's bombs turn back towards him.

$Greed$
Definitely one of the more annoying sins, though your trouble is often worth it.
Greed can either be found in shops or secret rooms instead of what you want
(treasure) and appears more frequently if you are carrying more cash with you.
Greed rarely gives any warning to when or how he will attack so either take him
out fast or be VERY careful.
Greed can either fire a quick attack of 3 blood balls in a triangle pattern
(hard to dodge!) or summon a pair of hoppers to assist him. Getting hit by
Greed's attack will cause you to drop coins and lose a coin off of whatever you
had total, so a net loss always occurs if he hurts you.
Defeating Greed grants you a pile of coins or the coveted Steam Sale.

%Lust%
Lust will come out sprinting. She can only chase you down like Gemini but she
won't stop for anything but the knockback of your tears. Slower moving
characters will get beaten down fast if they aren't careful as Lust always
deals a full heart of damage at all times. KEEP MOVING!
Killing lust will sometimes reward a pill, the Virus (cooties?) or Roid Rage.

&Sloth&
A rather slow and lazy fellow, he'll either spit chargers at you or cough up
exploding goo blobs. Sloth's attacks often kill off his minions, and he has a
limit of how many he can spawn, so just play it safe and he'll die pretty fast.
Sloth will usually drop a Tarot Card or, rarely, Bob's Rotten Head.

*Gluttony*
A fat little man with a big body... He will either quicky fire out a large
circle of blood balls (hard to dodge) or fire off his signature Blood Beam
(which he will telegraph in advance). Gluttony's room typically has a gaping
pit in the center, so use it to get some distance between you and him. Be
patient and he shouldn't hurt you too much.
Killing Gluttony yields hearts and sometimes (rarely) <3, the Bucket of Lard,
or the Raw Liver.

leave.

Shell Game: Giving him a coin will place a random reward into the shell on the
far right (coin, heart, key, bomb, skatole), which will be shuffled around to a

the Vendor to leave. Can be killed in a manner identical to the Beggar.

Blood Donation Machine: Donating 1/2 of a heart (1 heart in the Womb/Sheol)
will cause the machine to reward 1 or more coins (sometimes 6 or more if very
lucky). Repeated use of the machine raises the odds of the machine exploding

your max HP and boost your speed. Bombs can destroy this machine.

original position.

later than sooner.

1/2 SP damage from an attack fly as it comes from the Moter, rewarded with a

2 Maws. Path W to boss, S to arena. 1 Coin reward. Arena remains locked, to the
boss!
VS GURDY (crud...)
Fortunately/Unfortunately this seems to be the Champion DARK Gurdy... less
dodging but more killing. I use my Cookbook right off the bat. The rest of the
fight is a long, toilsome killfest. Unrelenting pooters bring me down to 1.5
Hearts, +1.5 from the boss and mom's underwear to boot.
Return and guess/find the Secret room which nets me 6 coins. A left behind full
heart brings me to 4 HP and opens up the arena...
Normal chest... 1 Bomb and 1 full heart :/ between my charm and the heart I
don't lose any HP overall. I curse my misfortunes and delve deeper.

18 coins, 2 bombs, no keys. 4 HP and 5 treasures. Not too happy. Base stats...
+1 Speed and +2 Range though. Not going to help me kill anything though.

MOM!!
My loadout was not really that good for dealing heavy damage and the battle was
costly. Mom leaves behind a Wire Coat Hanger leaving my stats at:
15 Treasures, 0 Coins, 10 Bombs, 2 Keys, 1 Pill (diarrhea), plenty of abilities
and 2 familiars.
My post-mom stats are: Max Speed, 4 Tears Rate, 4 Attack, 4 Range. 1.5/6 HP and
the book of Revelations which means for me plenty of SP to come.

I'm gonna stop here and let you explore the rest of BOI yourself, know that
your run through the game will be entirely different in every way. At least
this will let you know what to expect.
