Upon completing a very simple quest, I was awarded with the spell "Confusion". The description reads that the spell causes targets to attack themselves. The spell targets a 9 square grid and does insane damage to low, mid level and high level opponents unless they resist or have low attack values. The spell only costs 15 mana and can be used by ANY champion, including henchmen.

Once I was awarded this spell, there was no reason to cast any of the other damage spells and it could be spammed thanks to the fact that anyone can cast it.

This spell seems more than a little bit overpowered. Maybe the mechanics can be changed to give a temporary "clumsy" effect or the area of effect could be reduced to single target.
