Abnur Tharrn, but only if the remotely useless deathrecap tips get turned into sarcastic ones and he reads them out adding insults. "Whatch your step, halfwit".
Or, the 3 goblins from bards tale, bard song or so? who sing the "another chosen one bites the dust"-song everytime someone dies. could cause lag in cyro tho xD
The guy from bastion was awesome aswell
Edit: Oh, i forgot: The guy from vdsa! Hes amazing. First time i was there, he randomly commented "That was your healers fault", rest of the group was kinda amused, when i said "How the hell did he know?? O.O".
