The Chronicles of Masteria Update

This is something I've suggested quite a bit in the past. It's quite possible to program. Monsters can hit other monsters, we all know this from HPQ. However, the way this is written into the game is that Monster X can only take damage from Monster Z and Y. So, you could easily make it so that, say, Christopher Crimsonheart could take damage from each of the four Twisted masters, and that they could all take damage from him, but you couldn't accidentally hit Chris with your own attacks.

The only issue I really see with this is that you can't heal monsters (Though perhaps this could be remedied by giving Chris his own regenerative skill) so it might be tough to keep him alive. Such a plan would require a lot of testing because you'd want to make it worthwhile to have him fighting alongside you, but not make him do so much damage that you could just kick back and let him do all the fighting.

Maybe when he "dies," he would transform into a reactor that you could hit to wake up an X number of times. Or something that would need a member of the party to go to another part of the PQ alone to get another one of the masters.
