Just throwing this out here.
With the recent update you can now cast spells on the hightower_event map.
Maybe if someone makes a plugin to make this possible on all maps we might be able to make some bosses use these spells on rage? (like the bomb that spawns mini pumpkins that explode) it might make for some interesting bosses or even epic battles.

Think about it

Batman bats.
Pyrogas Fire
Merasmus blackhole?

Sounds like a good idea

Yeah, this would be cool... Also it would give some extra opportunities for making new and unique bosses using magic
