Leech do'nt work against magical attacks, and not sure it's still OP when you play on hard difficuly against end game ennemies.
Bloodletting and Teleport, boss.
And it is pretty OP even in Hard, especially around melee enemies. You could have one guy bleeding you and 3 other casters wailing on you. As long as you're bleeding or standing in your own blood (or theirs), it's pretty sufficient to solo kill almost everything aside from bosses.
