so where do i get the reflect rings, and where do i buy a more powerful aero spell than the first one? also where do i buy the gladius?
Unfortunately I don't remember where any of this stuff actually is. The gladius, however, I am sure is nearby. It may even be sold by the moogle in Eryuit (sp?) village. Check there for Aero spells too.

When you need to heal, unequip the reflect rings before you cast cura. Once healed, equip them once more.
