A cursed hunter-magnet ring that makes a killer exponentially stronger with each kill — and marks its owner for death on the sixth floor.
Mordecai reveals the true horror of the Night Wyrm's Ring of Divine Suffering that Frank Q gifted Carl as poisoned revenge. Several are generated every season, and their owners are the FIRST crawlers hunters track and kill on the sixth floor's hunting grounds — because in the hands of a sadistic combatant the ring's bonuses (a flat +5% to all stats, and Marked for Death) compound with every kill, raising the wielder's power exponentially. No Faction Wars army has ever been led to victory by a champion without one, so the rich tourists send idiots hunting to collect them, since the rings can't be imported.
Mordecai calls it evil, not meant for crawlers, and a lethal liability when magic-activating traps could trigger it. He forces Carl to pull it off — and Carl, feeling his stats drop, agrees only to sell it before reaching floor six rather than dump it immediately.
A green-glass ring set with a red jewel, worn on the finger.
A cursed power-farming artifact and a death-mark; the party's newest liability, slated to be sold.
