If you are melee watch out for Iron Maiden curse (Oblivion (LOL1111) Knights cast it for example), as its pretty much an instant death if you do a lot of physical damage. If you are a barb its good to have a point in Berserk as it does 100% magic damage, so Iron Maiden doesn't affect it. Every time you see one of the casters that cast it switch to berserk until the caster is down.
