mana shield is new skill in ice tree.
Its another ice buff. If the enemy hits u 10k then 10k is removed from ur mp and 5k(half of the real damage) is removed from ur hp. It lasts as long as u have mp. Its good for nukers, Str chars mostly cant use it cause they dont have enough mp.
U can get mana shield at lvl 20, then its lvl 1 and it removes 20%, at lvl 80 its maxed its 50%.
I took the 50% as explain
EDIT: If im wrong then im sry
