Berserker

• Unlike other Champion types, Berserker level is monster level +3 (the same as Unique monsters and their minions): this level is used for chance-to-hit, aura and curse level calculation, selecting relevant MonLvl values to calculate base attack rating and damage of all types, and the clvl/mlvl modifier applied to experience when clvl < mlvl; base level continues to be used to calculate base defense, life and experience.
