You wouldn't need to complete a Heavensward relic just use a completed Zeta for the 1st step. As it would end up using the completed Zeta as the turn in item. Otherwise you would have to do a grind via fates for the atma step.
Okay so thankfully I have completed Vital title, alongside Rise and Shine and Kettle to the Mettle. Once you have a Zodiac Weapon Zeta, there's no other steps to upgrade it further.
As I'm typing this I have lodged a missing item request for my discarded weapons.

Once I obtain a Animus Relic Weapon, will that unlock the ability to purchase Zodiac Weapon Replicas without needing the original? Or do I have to trade in one/all Zodiac Weapon Zetas to unlock the ability to?
