I'm leveling as a white mage, and I have this problem when questing;
I am running out of MP in the middle of boss fights... Usually when the boss have ~50% health left.

I am using MP restoration pots, but it doesn't help much.
Is there any way to avoid running out of MP? Do I need to play with some kind of rotation or use any special ability?

Right now I'm using "Aero">"Stone II">"Stone II">"Stone II">"Etc." + "Fluid Aura".
(Not much of a rotation. Heh..)
