"Recently, we have seen many players with several high-level jobs who have nowhere to store all their sets of artifact armor.
Until now, extra storage space has been provided in the form of Mog Safe expansions, furniture, and mannequins. However, we are currently working on a new system that will allow complete sets of artifact armor to be held by an NPC clerk.
Artifact armor for each job consists of five parts: Head, Body, Hands, Legs, and Feet.
If you trade all five parts to a certain NPC, you will receive a “claim slip” in exchange for your artifact armor. You can retrieve your armor at any time by talking to the NPC.
This new system is scheduled for implementation in the next version update.
