How about we make magic using similar to psychic powers in 40k?
As in, every time you cast even a simple spell, you need to fight off in the warp the various daemons trying to consume your soul?
So godlike powers are doable, just every time you cast anything there's the risk of an unholy monstrosity breaking the walls of reality through your mind and consuming your soul over the course of the rest of eternity?
Despite lack of mana bar, i assure you people will think twice before casting spells willy nilly.
