Grumpy the Yolo Barbarian(?) -- Solo HM - Nervous Lich 

I'm also using the Tiger Barbarian. A nice build for it is that weapon that you get from the Gnoll that heals you every time you hit + the necklace that makes you heal for the max amount or the necklace that adds poison to your weapon when you heal yourself. The rage AOE skill triggers the heal in all the characters you hit, so sometimes you heal for 36+ in 1 turn.
