[Murk]

Describe the issue: Berserk does not work at all. Not by its description and just in general (the desc reads as "If you deal over 500 damage within a 5s period, your global cooldown is temporarily halved. Duration of 30 seconds."). It may activate after the the needed damage and an red effect may appear around the char but, the effect thats listed under berserk does not work in any way.

How to reproduce: Simply use berserk on a giant character
