Notes from author
This was a very successful build, provided a lot of entertainment, rarely went beyond 15 seconds before the red eye brought me in for an invasion in any zone at any time of day (PS3). A lot of fair fights, had to go to Oolacile to get triple digit opposition (including one SL700+).
You can make this more effective by cutting int, att and end down a bunch and re-gearing. 40 poise is a very helpful thing, the health amount is just right because you want the red stone to trigger, the Estoc allows for elegant combat.
Enjoy watching your corpse burst and blow people up, and may your installs of this game never bug out in the ways mine did over the months long break I took from the game. See you in Dark Souls 2.
