Balance school needs a reflect spell that relects the next spell cast at him back at the caster. Reflect would have to have a low percentage chance of casting due to how powerful the spell could be.
I know pets like Jade Oni, Dark fairy, and some of the others are only set to one color. This gets boring. If you have a Oni, it's jade and so is everyone else's. Why not have an Oni pet that when you change it's colors it looks like a Death Oni or a Plague Oni or a Heliphant? Or a Dark fairy with other options?
