Aetherial mimicry

[Rongway]

Nice catch.

Maybe just put the augment effect in the same sentence as the beneficial effect to minimize the number of times it has to repeat that it's role based:

Mirror the aetherial properties of your target, augmenting certain blue magic spells and granting yourself a beneficial effect corresponding with the target's role.
If target is a tank, grants Aetherial Mimicry: Tank, increasing defense. [removed "your" for consistency]
If target is a DPS, grants Aetherial Mimicry: DPS, increasing critical hit rate and direct hit rate by 20%.
If target is a healer, grants Aetherial Mimicry: Healer, increasing healing magic potency by 20%.
Cannot be cast on self. Effect ends upon reuse.

They should even take it a step further and just drop the "If target is....grants" for each role, as the first line already says that it's role based, so all the if clauses are redundant.

Mirror the aetherial properties of your target, augmenting certain blue magic spells and granting yourself a beneficial effect corresponding with the target's role.
Aetherial Mimicry: Tank effect: Increases defense.
Aetherial Mimicry: DPS effect: Increases critical hit rate and direct hit rate by 20%.
Aetherial Mimicry: Healer effect: Increases healing magic potency by 20%.
Cannot be cast on self. Effect ends upon reuse.

And finally, just get rid of "Aetherial Mimicry:" in Aetherial Mimicry's own help text (it's fine to leave it as-is in the buff bar and other spells' help texts).

Mirror the aetherial properties of your target, augmenting certain blue magic spells and granting yourself a beneficial effect corresponding with the target's role.
Tank effect: Increases defense.
DPS effect: Increases critical hit rate and direct hit rate by 20%.
Healer effect: Increases healing magic potency by 20%.
