I don't know about life drain but Butter's healing does work like that.

Butters is best of you have the Brian food perk.

Mage=Jew>Fighter>Thief

S-tier Butters(Healing can also restore pp if you have the right perk) A-tier Kyle(massive aoe damage) Cartman(massive damage output) B-tier Stan(no real strengths or weakness) C-tier Jimmy(Support abilities arnt very strong in this game) Kenny(Once Kenny dies the other enemies will just gang up on you so you have to switch Kenny out when he dies, and he dies a lot)
