Pokemon stats explained! EVs, IVs, Natures, everything! PLEASE READ!

There are many misconceptions about how stats work in Pokemon. Allow me to explain the basics in this board FAQ.

How are stats determined?

Stats are calculated from a formula. This formula has been consistent since the third generation. And since the fifth generation, stat calculation always happens any time it needs to: end of battle, when stat-changing items are given, etc. The formula is as follows:

Stat = ((Base * 2 + IV + (EV/4)) * Level / 100 + 5) * Nmod

Except for HP, which is:

HP = (Base * 2 + IV + (EV/4)) * Level / 100 + 10 + Level

Everything rounds down.

Don't worry, I'll explain what each of these means!

Let's start with the "Base". What is that?

The Pokemon's base stats are determined by the Pokemon's species or forme. The only ways to change this are to evolve or change forme. Mega Evolutions have different base stats from their normal selves, too (except for HP; no Mega Evolution changes HP), usually higher.

You can look up a Pokemon's base stats on most good Pokemon fansites, such as Serebii or Bulbapedia.

Base stats are what the Pokemon would have at level 50 if it had a neutral Nature, no IVs, and no EVs... minus five in each stat (minus sixty for HP). So your stats will almost never perfectly match the bases. They're just a factor in the formula.

What are IVs?

IVs, or Individual Values, are hidden stats that every Pokemon has. They range from 0 to 31 in each stat, and cannot be changed without resorting to cheating devices.

At level 100, each IV adds one point to the corresponding stat, barring some skewing from Nature. That means up to 31 points per stat (again, ignoring Nature). As stats scale with level, you'll get less effect at lower levels; for instance, at level 50, it takes two IVs to make one stat point.

On a side note, IVs also determine the type of Hidden Power.

Wild Pokemon's IVs are determined randomly. That said, in the sixth gen (and not previous gens!), unbreedable Pokemon caught wild (that is, baby Pokemon, Nidorina, and legendaries - and theoretically Nidoqueen and Unown if they could be caught wild) will always have at least three perfect-31 IVs (maybe more, but never less than three.) The gift Celebi from Pokemon Bank will also have three perfect IVs, and expect this to hold for events for non-breedable Pokemon in the future.

Also, breedable Pokemon caught in the Friend Safari always have at least two perfect IVs.

So do I have to just catch a ton of Pokemon until I get one with perfect IVs?

Fortunately, no. When two Pokemon breed, three of their IVs are passed to the offspring; this increases to five if one parent is holding the Destiny Knot. While the RNG may not pick the most ideal IVs to pass down, good parents mean that the odds that the child gets good IVs are dramatically increased.

If one Pokemon is holding a Power item (Weight, Bracer, Belt, etc.), the IV of the stat that matches the item is guaranteed to pass down, but this does not work well if both parents hold one. The passed IV is counted the three that get passed down normally, but (at least according to Bulbapedia) it slightly interferes with the Destiny Knot and actually makes it so that it's possible that only four IVs pass down.

Whatever IVs are not passed down (three without Destiny Knot and one with) will still be randomized.

How can I see a Pokemon's IVs?

To get the exact numbers, you have to calculate based on their stats, and that requires you to know its EVs. There are calculators on multiple sites that will do this for you, but they're usually not precise until your level is high enough to account for the rounding. But fortunately, there's a good way to get the general idea.

There's a man in the Kiloude City Pokemon Center who will rate the "potential" of your Pokemon; he means IVs. Take note of the following:

First, he'll rate your Pokemon's entire IV total.

If it is 90 or fewer, he will say that it has "decent" potential.
91 to 120, he will say that it has "above average" potential.
121 to 150, he will say that it has "relatively superior" potential.
151 or more, he'll say it has "outstanding" potential.

Next, he'll rate your highest IV.

If it's 15 or lower, he'll say it's "rather decent".
16 to 25, he'll say it's "good".
26 to 30, he'll say it's "fantastic".
For a 31 IV, he'll say it "can't be beat!"

He'll make note of ties for the highest stat. Also, any stats that have an IV of zero will be commented upon as well.

What about Nmod? What is that?

(Yes, I skipped EVs, I'll get back to them.)

Nmod is shorthand for "Nature modifier". Every Pokemon has one of twenty-five Natures. Twenty of those Natures boost one stat by 10% (marked in red on the Pokemon's details page) and reduce another by 10% (marked in blue). The other five do nothing at all, and no Nature modifies HP.

So the Nmod is 1.1 for the boosted red stat, 0.9 for the reduced blue stat, and 1.0 otherwise.

Natures are determined mostly-randomly.

Mostly randomly?

If your lead Pokemon has the Synchronize ability, you have a 50% chance of any given wild Pokemon having the same Nature. And when you breed Pokemon, if either parent is holding an Everstone, the baby will be guaranteed to have the same Nature as that parent (if both parents hold an Everstone, it will randomly have the Nature of one of the two.)

So how about EVs?

This one is the most complicated to explain, but it's really not that bad once you get a feel for it. Some math skill will help, too.

EVs, or Effort Values, are another hidden stat that indicate the Pokemon's training. Defeating enemy Pokemon, eating Vitamins, going through Super Training... these are all ways to gain EVs.

You have much more control of EVs than IVs, but there are limitations upon them. Most notably, Pokemon are limited to 252 EVs (in this generation) per stat, and 510 EVs across all six.

The limit per stat used to be 255, but was changed to 252 in this generation. A 255-EV Pokemon that gets Transported will have its EV reduced to 252.

EVs only matter in groups of 4 (which is why the per-stat limit was reduced; 255 EVs meant three were wasted). At level 100, ignoring skewing by Nature, each set of four EVs applied to the same stat adds 1 to the stat. The maximum of 252 EVs comes to 63 stat points, and 510 EVs all around means 127 are available between all six of your stats (and two EVs are useless, which can be considered insurance from screwing up slightly). Again, lower levels scale this and nature skews it.

510 EVs allows for two stats to be maxed and a third stat to receive four more useful EVs, but this is not the only way they can be distributed.

The Laverre City Fan Club president will give a Ribbon to a Pokemon with 510 EVs.

(still more coming!)

How do you get EVs through battle?

Each Pokemon species grants between 1 and 3 EVs when defeated. Everything that gets EXP also gets EVs in full, including when the EXP share is active, when the Pokemon was fighting the enemy but switched out, and when the Pokemon is captured (in the sixth gen), but not when the Pokemon is knocked out. EVs are not split; everything that can get them gets all of them. The level of the defeated Pokemon doesn't matter, only its species.

Most Pokemon give EVs in the stats they excel in. Weak and unevolved Pokemon typically give 1 EV, moderately strong Pokemon and those that have evolved once usually give 2, and legendary Pokemon and those that have evolved twice generally give 3. For a list of what Pokemon give which EVs, I again point you to fansites like Serebii and Bulbapedia.

If your Pokemon already has max EVs in the relevant stats or total, then nothing will change; no EVs will be lost and none will be added.

Any way to get them faster?

There's a rare status called Pokerus, which spreads from Pokemon to Pokemon in your active party as you battle if any of them have it. It wears off after a few days in the active party, but this only means it cannot be spread. Pokemon that have ever had Pokerus - even if it has worn off - receive double EVs from battle.

There are also items that affect EV gains. The Macho Brace doubles them; the Power items (Weight, Bracer, Belt, etc.) automatically add four EVs to the stat that matches them with every Pokemon defeated in addition to the EVs the Pokemon normally gives. Both of these stack with Pokerus, meaning it is theoretically possible to get 14 EVs from a single Pokemon (if the Pokemon gives 3 EVs, your Pokemon is holding a Power item, and it has Pokerus: (3 + 4) * 2 = 14.)

Hordes are a very powerful EV-training tool, if you have Pokerus and a Power item. A horde of 1-EV Pokemon will give 50 EVs to a Pokemon with both, and a horde of 2-EV Pokemon will grant 60! (There are no 3-EV Pokemon hordes, but if they existed, they'd grant a whopping 70 EVs.)

Though multiple Pokemon can get EVs from a single opponent, only the ones that actually have Pokerus or the boosting items get any effect from them. That said, it doesn't matter if the Pokemon is actively doing the fighting or just sitting back and absorbing the EVs through the EXP Share; the boosts still affect it when it has them.

What are some good places to fight hordes for particular stats?

Remember to use Sweet Scent or Honey to attract hordes... and that you can't attract them if it's raining on the overworld. I'm compiling information from Smogon for this.

HP: Route 5 (Gulpin - 1), Connecting Cave (Whismur - 1), Route 20 (Foongus - 1)

Attack: Route 19 (Weepinbell - 2 and Arbok - 2), Route 14 (Bellsprout - 1 and Ekans - 1)

Defense: Terminus Cave (Durant - 2, Geodude - 1, and, in X, Aron - 1), Victory Road (Geodude - 1 and, in some caves, Graveler - 2)

Special Attack: Frost Cavern (Vanillite - 1 and Smoochum - 1)

Special Defense: Reflection Cave (Mime Jr. - 1)

Speed: Route 8 (Wingull - 1 and Taillow - 1), Route 12 (Wingull - 1), Route 15 (Murkrow - 1)

So maybe I don't want to get EVs from battles. What about these Vitamins?

Vitamins (HP Up, Protein, Iron, Calcium, Zinc, and Carbos) can be obtained in various places, most notably bought in the Battle Maison (2 BP each) and Laverre City's Pokemon Center (9800 Pokebucks each).

These items give 10 EVs to the appropriate stat instantly, but cannot take a stat over 100 EVs (regardless of how those EVs were obtained), so always use Vitamins first. Pokerus and Power items do not affect Vitamins. They're a good quick start to EV training, but given the 100-EV limit, they won't finish your training for you.

There are also Wing items that can be obtained more rarely. These add only 1 EV each (except the Pretty Wing, which doesn't do anything at all) but work up to the usual 252 limit instead of 100. Again, this is not boosted by any means.

And what of Super Training?

Super Training is a new mini-game you can play to increase your EVs.

The main training has you shoot soccer balls into a goal tended by a Pokemon-shaped balloon, while avoiding balls hitting your own goal. You start with level 1 training. A successful level 1 game will grant your Pokemon an instant 4 EVs in the stat you were training.

Once you've completed all six level 1 training sessions once, you open up level 2 training, which grants 8 EVs per game. Beat all of them to open level 3 training, for 12 EVs per game. After you max your EVs on a single Pokemon, you can play "Super Secret" training for items, but since this is a topic about stats, I'll not go into details on that here. Pokerus and Power items do not affect Super Training.

The higher your EVs, the easier the Super Training games are, and each stat boosts some aspect of your Pokemon's performance. Different Pokemon shoot the ball differently in Super Training (some charge the ball, and some shoot rapid-fire. It is generally agreed that rapid-fire Pokemon have a harder time winning.)

You also get punching bags for completing Super Training regimens, and also for having your Pokemon punch the default black bag on the Super Training screen. Some of these bags affect your EVs as well. Once you select a bag, your Pokemon will automatically punch it once per minute, or you can tap on the bag with your stylus rapidly to speed the process along. A small stat bag will grant 1 EV, a medium 4, and a large 12. There are also bags that influence how many EVs you get from Super Training, and Reset Bags, which I'll get to further down.

Any other ways to gain EVs?

The Juice Shoppe, on Lumiose City's Autumnal Avenue, can sell you drinks (or allow you to make your own by mixing two berries). The colored drinks (which can be made by mixing two berries of the same color) grant between 4 and 32 of a given EV.

Purple = HP
Red = Attack
Yellow = Defense
Blue = Special Attack
Green = Special Defense
Pink = Speed

If you're buying the drink, the number of EVs you get are equal to how many hundred Pokebucks you spend to get the drink; that is, a P600 drink gives you 6 EVs, and a P2100 drink gives you 21.

(one more!)

What if I don't like the way my EVs are arranged? Can I remove them?

Yup!

First of all, one of the punching bags you can get from Super Training is a solid-white Reset Bag. Any Pokemon that punches this will have all of their EVs sent back down to zero.

You can do the same thing by mixing a Perilous Soup at the Juice Shoppe. This requires one Kee and one Maranga Berry.

If you just want to fine tune them a little, there are certain berries that reduce an EV by 10. These berries are:

HP: Pomeg
Attack: Kelpsy
Defense: Qualot
Special Attack: Hondew
Special Defense: Grepa
Speed: Tamato

Removing your EVs will also lower your stats, so you can't abuse the system. But it lets you retry a bad spread.

EVs never disappear from your Pokemon unless you do one of the above; they are otherwise permanent. Gaining levels, evolving, trading; none of this affects EVs.

How can you check how many EVs you have?

Super Training has a hexagon-shaped chart that will give you a rough idea. The yellow region represents your EVs. Too vague? You can do better.

Save first. Did I mention save? You'll be sorry if you don't! So, now that you've completely saved...

Punch a Reset Bag.

This removes all EVs from a Pokemon, and as it does so it will show exactly how those EVs are changing on the hexagon grid. So if you see see a -120 next to a stat, that means your Pokemon had 120 EVs in that stat.

And now doesn't any more, so unless you really wanted to remove the EVs, you'd better reset!

How do I know which stats I should train in?

It's completely up to you! Sites like Smogon give suggested EV builds, but you don't have to follow them. I'll just say this: most people train offensive Pokemon in Speed and the Attack stat they use, while defensive Pokemon usually get HP and the lower Defense boosted, unless its HP is high enough relative to the defenses. But I have no gun to your head. Experiment!

When should I start training the Pokemon? At level 1?

Doesn't matter. But if the Pokemon has seen battle already, it may have EVs you don't want, so you'll want to erase those first.

How many EVs should I get per level?

Doesn't matter. EVs are not given on a per-level basis. EVs are EVs and levels are levels.

Are EVs why Rare Candies are bad?

Rare Candies are not bad. There is no negative side effect to using Rare Candies.

So if I get 4 EVs, that means I'll get 1 point of stat gain when I level up?

No, that's not how it works. There is no such thing as "stat gain" in Pokemon, at least not of the Fire Emblem sort. The Little Plus Numbers (LPNs) you see when you level up don't mean anything of value and can be safely ignored.

And that's not dodging the question. It's not at all impossible to receive a +0 LPN in a stat you've been training, especially in the later generations where EVs are applied to your stats immediately after you get them.

I trained up to 252 EVs in Super Training, but my level 20 Pokemon barely has 63 in its stat at all, let alone from EVs! What gives?

The 63 point boost from having 252 EVs kicks in only at level 100. At level 20, you'll only get 12 or 13 points in a Nature-neutral stat from 252 EVs. Don't worry, those EVs will still be in all their 63-point glory there once you've hit level 100!

Can I gain EVs at level 100?

You can't through battle in the third or fourth generations. In any other generation (including, sort of, the first two, though the system was quite different then), yes, you can EV train through any method at level 100.

I included much of the same information, and being the same person I of course worded things similarly, but extremely little was copy/pasted.

Also, it's most useful having all the main information on the front page. The last topic barely even mentioned IVs and Natures.

You can't edit posts outside of an hour, so that wasn't an option.
