Well, the title says all pretty much.

Having the Zeta Weapon in your possession is still a requirement for getting the replicas from the old Relic Weapon quests. I know this, since I did do my relic weapon quest completely, but I accidentally sold/dropped my Excalibur + Aegis Shield Zeta. I already contacted the GMs about restoring it and they said they can't because of the special properties of the relic weapon.

So here I am with the suggestion of making removing the requirement to have to have the Zeta Weapon in your possession to get the old relic weapon replicas. I think that the only requirement should be completing the quest you get the Zeta weapon from (The Vital Title).
