Since I haven't played a regular game of Warcraft III lately I'm not exactly sure what spells/effects/buffs do what. I'm looking for one that slowly degenerates your health, could you tell me what spell/effect/buff does that?
So does Unholy Frenzy (I think that's the one the necromancers have), all you have to do is remove the speed bonus and then all it does is degenerate health.
