So for summoners they have the ability to egi glam. Which includes "downscaling" their egis into carbuncles.

I'd like something like that but for all spells. Just like the carbuncles it'd be purely cosmetic and not effect potency at all.

This would allow you to use the spell animation of a lower level spell that is directly replaced. So like instead of glare on a white mage you could get access to stone II. Instead of Dia you could use aero.

While they are often less flashy I find some of the older spells to be better, particularly thematically.
