The Chosen Ones

So if i make a little combination of few things from campaign, the int phodom is unbalanced
If u combine the aura of fire + magic aura + phodom's set + zocmo's set/unholy cloak/ring of thunder(the idea here is the invisiblity) you can easily kill bosses without even hitting them.

Does they hit back to you?

Yea I get the point but you didn't gave me any idea how to fix the problem. If it's even the problem. I've been thinking that it's in the end fine. I mean you can't make all your characters magic based so you're forced to have maximum of 2 characters magic damage based.
