trying to add some balance to my magic system

[kidwitthafro]

I use midas magic, and it is amazing, however I'm trying to make my magic system a little more challenging, and a little less overpowered.

 

I want to either, slow down the rate my magicka regenerates to a crawl, incorporate the sleeping system that is used in fearsome magicka: after a set amount of spells, the player must sleep to be able to cast them again, or give all of my spells a greater-power like property--I can cast up to x amount of spells per hour/day etc.

 

Furthermore, I'd appreciate a way to give the enemies in my game, namely enemy mages, the ability to cast midas magic spells.

 

Any help is appreciated!
