Þetta er copy paste af battle.net. Kmr Resistant Skin Gives Mountain Giants increased resistance to spell damage. This gives the unit hero magic resistance, similar to the resistance that level 6+ creeps have. Namely, you can't be Polymorphed, Possessed, etc, and all offensive spells have a shorter duration on the target (such as stuns, Ensnare, etc). It DOES NOT reduce damage dealt to the target, however. That’s an effect of hero armor, not hero magic resistance.
