My Zeta is only worth 18 atma?

If you don't want to destroy it, Grind it yourself. @.@

Also, your Zeta is worth all the advantage it gave you in ARR~Early 3.0. If you started after 3.0's Launch that might be an entirely seperate issue. Also, the Galmour. : D

except this: "Although the Zodiac Weapon Zeta will be lost upon exchanging it, players may purchase replicas should they choose to preserve its appearance via glamours."
So, there is absolutely no point in keeping it.
