might be for the anima weapon. 1 item per floor.
or it might be a token system, where no matter how bad you loot you'll eventually get to choose an item. again 1 item per floor, so no need to add more.
or wild guess, considering how SE is basically throwing ilv210 gear at us, these might give us a chance to upgrade prototype gear to real gordian gear, but the items will obviously have a low drop rate (this one is unlikely though, since there was no mention of any new additions to the idyllshire npcs)
