Notes from author
Note: I recommend starting as a pyromancer as the increased resistance boosts the defence slightly (without wasting any points on anything else in terms of the final build).
A sorcerer build that depends heavily on magic damage, the huge and glaring disadvantage of this build is the fact that you'll probably be overpowered by faith builds using Magic Barrier, you can also be overpowered by people that just have a high magic resistance in general.
On the bright side you'll be able to deal massive damage with sorceries and whatnot. Since you can't buff the Moonlight Great Sword you'll be stuck with 480 damage.
Remember if you're planning to go into NG+ while also going towards copies of the crystal spells, you can replace the originals with these copies to be able to deal more DPS.
This build is definitely for advanced players who aren't faint of heart, good luck.
IMPORTANT NOTE:
Starting the game will be very hard compared to most other builds that use str/dex weapons, since you will be limited to 10 dex and 16 str, be cautious.
It's important you find something that scales with int as soon as possible.
You'll also need to keep a weapon in mind so that you can actually deal damage when making the trip to the Duke's Archives (And to cut Seath's tail for the Moonlight Great Sword), you could easily grab the nearest claymore and buff it with lightning, this will make your journey through Duke's Archives much more bearable.
I recommend using pyromancies at the early stages of the game, since if you start as a pyromancer, you'll be able to cast these at an early stage.
