IBM Conspiracy V2 - Ice Demon, Big Bang and Mana Reflection

The point of Fire/Ice Demon is to make mobs weak to Fire/Ice, respectively, and the most important aspect of both is the number of mobs that they affect.

I don't think it's really worth all the set-up to have a x1,5 multiplier on your BB damage. I'd rather just use BB then, unless it's mob that takes more than 1 big bang to kill AND comes often in mobs of 5 or 6.
