Up in Arms, Atma Farm

Speak to Jalzahn in North Shroud (X: 30.0, Y: 19.0) to unlock the Relic Weapon Zenith Enhancement option. Obtain all 12 Atma by completing FATEs in the listed zones with your Zenith weapon equipped. Drops are not guaranteed.

The Atma dropped are job-agnostic, so you may farm all of them at once without picking up the additional weapon quests. Only one of each Atma per job is required to enhance that job's weapon — if you intend to farm the relic for all ARR jobs, you will need 10 of each Atma total.
