I find that it is amazing when used with fire pets but I can only say that much. I personally see it as higher critical rating, with the loss of actual power. See the thing about that is the bosses block, if you can manage to get the robe AND the hat it should lead to a great spamming combo. But overall I find that it is better, just hard to obtain.
