Simplicity's Strength and The Grin Reaper

Hello.

Dear Witch Doctors, and everyone else. I just got the Gem Simplicity’s Strength which gives an increase in the damage of primary skills. Would this work together with the helmet The Grin Reaper, so that when the mimics cast primary skills, those would also do increased strength?

My mimics use primary skills all the time, so that would be quite a damage boost if they work together, but I am not sure if they do? Is this gem worth levelling?

A rule is proc can’t proc.
So, I guess the answer is NO.

works best with helltooth Zombie charger/acid cloud build. to bad the specc is soo bad atm u cant even do T16 with it. it needs a big boost.
