Steps:
1. Upon completing the above Avatar fights, I am able to choose from a list of rewards that I can only obtain once.
2. Over the years, these items can be accidentally discarded when clearing inventories, or dropped intentionally to make inventory space as they cannot be sent to other characters on the same account or stored on an NPC.
3. Other quests with rewards of similar calibur are reobtainable, but these are not.
4. Moving forward, could there be implemented a way to reobtain these items? Similar, perhaps, to the Artifact Armor quests of having memories wiped away or a new key item to obtain the rewards.
5. I know I am not the only player that is interested in being able to obtain these items again. http://forum.square-enix.com/ffxi/th...e-Interference

Apologies if this is not the correct forum, I was informed by an in-game GM to post here in the In-Game Bugs. Thank you.
