Honestly, something that would have been neat is having spells tied to Mana Meter, maybe have a spell like:

Vermedica - AoE Cure that costs 10 white mana

Verwater - High potency Nuke maybe 400 that costs 10 White Mana triggers Verstone automatically

Or

Verblizzard - 400 potency uses 10 Black Mana automatically gives Verfire ready

Would be neat to use our manameters for certain spells.

That was just a thought though lol.
