in the wiki it says crafting jawbones gives you 2,5 magic damage per level, but in game it says it adds to maximum magic damage. Does this mean I'm not actually doing the damage? Because if it does, I just wasted a perfectly good weapon.
Actually, the abillity "adds max elemental dmg" (fire, ice, lightening), means, that you get a elemental dmg bonus of 1 to (max dmg). For example 1-500 (with lvl 100) fire, ice and lightening damage (3-1500 actually, due to threee bonuses).
I hope i could ease you, about your weapon.
