Notes from author
This is a build I have designed for twitch plays dark souls. This is a dex and pyromancy build based on the fact we cannot block. This build has a powerful and long range dex weapon and a mix of powerful pyro spells for bosses and regular pyro spells to get through as many enemies with ranged attacks as possible. It has tons of health and decent armor, and a ring that improved rolling, our only real way of defense.
The Great Scythe is a treasure in the Catacombs. The pyromancy spells can all be gotten from an NPC in the depths(which moves to firelink after freed), and in Blighttown.
I would also recommend we get the Uchigatana from undead burg by killing the merchant to serve as our main weapon until we can get the great scythe.
