Cursed enemies take damage = to their mana when casting spells 10% chance per turn for it to wear off
Confused enemies have their mana ( sources ) colors randomized. 10% chance per turn for it to wear off.
Confusing would not reduce their mana colors just what color of mana. EX: a confused mythic would still have three mana sources. Say you confuse a kraken and his mana colors go from Green/Purple to Red/Black
