Fun with Shadowkeeper

Alright we all know you can solo a game with a sorcerer or you got the nice party consisting of tom dick and harry. But what about having fun for a change and see what you can pull off with that shadowkeeper. Right now I'm doing the following

Avatar of Bhaal: Apocalypse Now

Pretty much I'm using a dual Assassin/Mage(shadowdkeeper, it runs buggy) and I made each class 20/20. I gave him 25 in everthing and I gave him the best equiptment he could use right off the bat. In Irenicus dungeon where I am starting out I killed all the NPC's. Pretty much the object of my current game is to kill every character. I've had to restart and redo several times due to you cant killing certain NPC's or it will mess up the storyline. I am keeping with being an actual Avatar of the dead god Bhaal. Just kill everything. I even Cluaconsole people in to kill. Fun I say. my rep is like -20
