This thought just crossed my mind considering the design of Occult, but I wonder how it would work out if they actually revisited the "Chain" gimmick that was originally designed for leveling and currency acquisition. Given that CE/Chest and such give currency now, the Chain mechanic is not as useful as it once was as people can just farm CE for the accessories however, if they put in a system where every 20 chain each player gets a free "pot-like" chest to appear on the map it would encourage players to partake in the chain gimmick.

As far as I'm aware we currently have a hard limit of 30 bronze chest, 3? Silver when it comes to chest that can spawn through CE, so if you just add in a new chest that can spawn in the "pot" locations, then every 20 chain hit a pot chest will spawn in one of those location but you can only have 1 of those chest types spawned at any given time. So as a party you would chain 20, hunt the chest, chain 20, hunt the chest, rinse repeat until bored or you get the accessories you are farming. With that in mind I would remove the gil reward from these chest and just have it where these "pot-like" chest just have the same loot table as the pot chest without the gil.
