I know I'm late to the whole Dark Souls party, but. . .
Here is a link to a full walkthrough of the game with full commentary. It began as a pyro focus build to help new players break the game early, but a Black Knight Halberd drop changed that. Either way, this is an efficient path through the game that any gamer can emulate.
NOTE: This was recorded from console and DOES NOT have the new DLC included. My channel however has boss videos against all the DLC bosses.http://www.youtube.com/playlist?list=PLTaOHX8kEkD4Uh62ZXtLsc...
Hope it helps
