The next rarity after rare will be legendary, as you can tell by looking at the dismantling gui, you can see info about legendary crystals. There are currently no legendary items in the game on floor 3, but there will mostly like be one or two after floor 4 public release

Back when floor 3 was released and rare items were added to the game (other than crafter's outfit), the drop chance was originally 0.01%, due to the devs and player confusion/compliant over what the fraction was equal to in fraction form, the devs later increased it to 0.1% which is equal to 1/1000 and then finally what it is now 1/500 or 0.2%. Anyway, one of the devs told me that the drop chance for legendaries would start at 1/10000 unless the community riots once they realise how hard it is to get legendaries, trust me, its going to be countless hours of farming.
