How far along is the magic? What is the limit? I'm making a race that is attuned to a certain element for elemental magic.

Magic use carries a simple principle in this RP, perhaps I didn't explain it well enough.

The bigger the spell, the bigger the life drain on the caster.

The more frequent the casting, the more exhausted the caster. 

As wizards and mages train, they'll find ways to reduce the drain of their spells, and make them more efficient. 

Everyone else is welcome to jump in here, I sense that it may be a hot topic. I thought my interpretation was preferable to the idea of 'mana', but what say you all?
