That must be it ;) . And I'll hopefully be staying out of mêlée combat, so those others hopefully won't ever activate ;) .

I suppose the damage is rather low. When maxed, it only does 78-80 damage. And this is reduced to a third for ranged weapons. But it does boost me and my merc a bit, and I wouldn't know what else to boost for my character. I won't need much warmth because I won't cast spells, and I won't need energy shield because I don't have much mana, anyways. And almost all the other skills are spells I don't want...
