Strife:Blunt Chitin Halberd of Battlerage

Each time you are hit and SV applies, you gain 2d(Character Level) points into your rage reserve, in combat only. Rage reserve resets to 0 after finishing combat. Each time you hit a target, you roll d(points in rage reserve) in piercing health damage. The rolled damage you do is divided by your Character Level and taken away from your rage reserve.

Note that though it is listed with 400 durability, this is non-important as it deals no physical damage therefore will not decrease.
