retribution alone won't cut it for a lot of undead who deal poison damage. as decay doesn't work for that damage type anymore it seams - looks like it only applies to true healing from hydro/first aid/potions.

lone wolf is a given. living armor and picture of health if you pick up warfare might not be a bad idea
