My plan for Ulin the white was that he should appear on the screen to "drain" the evil wizards. You must keep them occupied while he works.

As he drains them, their powers get less. It will take him quite a while to do because he is the only one doing it. If he gets hit while he works, he will teleport out of the screen to heal himself and then teleport back in again to continue.And when he's done,you can use that wizerd he drained and can switch wizerds drained and they all have different spells.
