So, we have relic weapons that can be updated, but how about a relic spell or ability? Hear me out:

The Relic spell or ability is available at 50. Each job gets their own ability. Need to have the relic weapon first. The ability is gained from a quest just like job quests. The ability can be relic bound or free (depends on how the devs balance it)

Relic Bound: Can only be used while the Relic weapon is equipped.
Free: Can use used regardless of weapon.

The ability is something that has to be iconic for the job it is applied to.

For example, PLD gets "Hold the Line". They crash their Holy Shield into the ground and bunker behind it. Defense doubles but they are Bound, Pacified, IE can't act or do anything for the duration. The duration starts at like 5 seconds, but as you upgrade the ability duration increases. Or wait, that's a little too close to HG. Maybe they get like "Enlight" or something. Give them religious undertones since their shield is called "HOLY SHIELD"

WAR would be "Enrage". For the duration, WAR do not consume Infurate when using the abilities that cost Infuriate. So they can spam SC non-stop while Enraged.

MNKs could get "Hundred Fists", etc.
----------------------------------------------

The idea here is to make Atma farming worth it. If you have the disciple to keep at it, you get a relic weapon, and a cool ability for your time. Of course, now that I wrote this, we'll prolly see "Relic ability onry NOOB!" in the PF lol.

It would be kinda hard to balance it, but still....I would like to see Relics as the best weapons in the game. Right now, why would anyone get an Atma weapon, when Levi weapons are just as good. They are friggin LEGENDARY weapons, they should be the BIS. But, they are practically handed to you at 50.

These abilities could also function like a personal Limit Break people seem to want.

Maybe Novus weapons will blow everything else out of the water.
