One of the most coveted treasure-hunter prizes, which Carl holds and dangles as bait to draw every hunter to him on the next floor.
The Ring of Divine Suffering is among the most sought-after items in the dungeon, prized by treasure hunters — and Carl holds it. Mordecai repeatedly, urgently demands he toss it, warning he 'can't tempt fate' against the forces he's provoking. Carl refuses: as he descends, he holds the ring up to the unseen cameras and openly taunts the galaxy's hunters, offering it and the Gate as bait — 'Come and get it, motherfuckers' — vowing to hunt and kill every hunter who dares share his floor.
The ring becomes the centerpiece of his 'seeding the pond' strategy to lure enemies onto the sixth floor where they can truly die.
A dark, ornate, highly-coveted magical ring.
A coveted artifact Carl uses as bait to bring the hunters to him.
