Well that makes sense for practicing magic. But for learning magic, I guess it does take a time when Studying a Tome of Magic.
I noticed when my sims were doing extensive spell casting their energy depleted rather Quickly, which I really love. Magic is a form of energy, and should feed off of the Sims Energy Gauge rather than some Magic Meter, or whatever. It's just you ought to be careful about how you use your magic. I think, Not 100% sure still trying to study it, but I think, if you have a good Charge then you Energy needs won't be touched as much, but don't over do it. Magic indeed comes with a price... dearie.
