Cast on Crit wont work on my invoker.

I have tried many many things to make this work but I cannot get my Cast on Crit work.

My Cast on Crit has Profane Ritual in it, when I turn it on it will not reserve any sprit and it wont work. It only shows turn ON but it will not reserve sprit nor work as it should be.

I emailed support@grindinggear.com and attached pictures there, and I was advised to post in here.

I LOVE this game and I tried SOOOOO hard to fix it.

PLS help me.
