Ok, I got this spell expecting it to be a strait on upgrade to Fury. It is not. First, you must be berserked to use it. For those who remember, in early beta zerkers had to be zerked to use nearly every skill. On greater fury it does not say that you need to be berserked. I am guessing it is bugged. It is also stacking with regular fury, but I am not sure I am getting the stacked benefit. Just wanted to throw this out here, see if anyone knew more about it.
