I recently got my hands on one of these from Kedala. Here is the link to the mask: http://us.battle.net/d3/en/item/the-grin-reaper
It's a cool mask. But does the mimics actually do any damage at all?
Firebats seem to proc them pretty often so they are always there, but what is their own proc rate of casting a spell? I've seen them cast Firebats, Zombie bears. But their proc rate of casting spell seems variable, they seem to cast Firebats all the time, but cast Zombie Bears once in a while, Grasp of the Dead very very rarely and never cast Piranha.
Which spells benefit most from these mimics, could anyone knowledgeable shed some light into it?
Another question; right now I'm using Firebats as my main damage spell. I've got 13% Firebats damage rolled on the mask, is getting a 6% CHC worth more than this one DPS wise?
