That's the idea. I play on another site dedicated to Fairy Tail and when she get's higher level spirits there (spells have their own ranks) they cost her more magical power to summon (dismissing is free though, far as I'm concerned).But yeah, the stronger the spirit, the more it cost, just like Lucy and her Celestial Spirits... wait I have yet to read the latest chapter!

Note: Please don't discuss what is going on in the Manga as some people here only follow the anime (myself included). In general try not to discuss recent events in either. But older arcs and events are fine.
