ITT: TMK makes a viable suggestion, TC shoots him down without any real basis.
Astora's Straight Sword is a great starting item for any cleric class, comes with a dragon crest shield to boot.
If you want to pump only faith the @$$ sword is great. My SL33 sunsista wrecks things with it at plus five. Unfortunately it is pretty bad for sens and AL. I can wreck the gargoyles in 3-4 hits. Just an idea for a "silly" build.
Dex pyro posted a pretty cool weapon selection for my tastes, the great club for str is a no-brainer, the falchion for low regular and for bosses is nonsense-what-alien Jordan, spam R1 and don't even dare to look at the screen, for mid regulars or pvp i prefer something more ranged or with pokes.
If you want to stay with the BK thing go for 36-18/40-18, your next toy may be black knight halberd and black knight axe, both awesome, easy to get, and easy to upgrade, if you go for pure quality (28/40) your weapon selection will be wider, try + 15 murakumo and any halberd you like, don't make it chaos, don't worth it.
u can make a weapon +15 before you ever beat the gargoyles
acquire weapon for plusfifteenage
farm shards, chunks, and get slab from asylum stray demon
get ember from depths and new londo (gargoyles do not have to be beaten to access the depths, just get the key to undead burg from gate by armored boar)
My mage character has a Winged Spear +15, Great Scythe +14, Enchanted uchigatana +4 and a fully maxed out pyro hand at sl22 and standing outside the gargoyle church gravelording :3 only bosses beaten are taurus deamon(if i could i would have skipped him too, but i wasnt thinking) the demon that gives the key to the depths, and the stray demon.
Wow power well done. Mind if I ask how you did all that? Some of it i can understand via farming, slabs and such in the hollow, etc.
but the scythe and the uchi are quite impressive.
Basic farming (lol at 'basic'. darkwraiths hit like a truck at early levels and equipment) for the shards. Balder guys for shards and i just buy them, the slimes in the depths for large shards, and darkwraiths for chunks. The most annoying thing is farming the blue crystal golems in darkroot to get blue chunks! So rare.
Always complained about the low level early area 'griefers', but with this build ive taken down many giant armors/lightning weapons, even a few persuer casters. So i guess technically im griefing, but im gravelording, its your choice to keep invading :)
