It looks like a physical damage zealot with holy freeze on only for dealing with PIs and giving the slow aura. If you are going to play like a zealot, you gotta find from your mercenary whats missing from your lack of fanatism (or you have beast, but I think a higher damaging weapon would suit you better)
So, yes, blessed aim unless you want might. You could give a beast weapon to your mercenary.
And, myeah, what am I on

Meant 6 facet weapon. But of course without the ITD i would need additional AR. The armor is one of the only thing giving me resists, I need to keep it for any kind of decent protection against gloams, etc.
