Armor Glamours

[Enkidoh]

I'm sorry to say this, but no there is not. Yoshi made it quite clear years ago (back during the Beta test in fact) that he wants each class/Job to have it's own unique identity, and that means no cross glamouring of class-specific gear.

The whole point of Job specific gear (Artifact Armour or 'AF' for short) is it is meant to represent the classic appearence of that Job in past FF games (or at least aspire to), so hence why you cannot use PLD AF on your AST for instance (as I recall Yoshi specifically used the example of "not wanting a WHM to look like a PLD" to explain his feelings on the subject).

There is at least one glamour armour set available that you could use on your AST if you still want an armoured caster look (the Legacy Warrior's set rewarded in a past Rising event, which is now for sale on the Mogstation), but AF especially will always remain Job locked as that it's whole purpose for existing in the first place I'm sorry to say.
