The Goal is to stay near monks and if they need energy they use Blood is Power and blood ritual. After using those two they target foes and if the foe has a enchantment instantly use Strip Enchantments for health. If not use enfeeble on a Warrior (Preferably hammer since they are very strong against low armor dudes) to knock down their attacks. And basically just use Defile Flesh on an Opponent so they get less healing. Keep monks energy up and yours and keep destroying those enchantments and you got it made.
If you're doing PvE then you might consider Well of Blood. There are going to be plenty of corpses around so you might as well make use of them. Of course you need to get that straight with any other corpse users on your team first.
