The Ring of Divine Suffering is an enchanted item that grants its wearer a modest increase to every attribute and the much more dangerous Marked for Death skill. A successful mark converts another combatant's death into a permanent gain in whichever attribute was highest for that target. An active mark prevents the wearer from healing until the target dies. Carl receives an Enchanted Night Wyrm's Ring of Divine Suffering from Frank Q on the third floor, carries it through several floors, and ultimately gives it to Princess Donut to swallow. Other rings affect Prepotente, King Rust, and Li Na. Their uses show why the item is prized by both crawlers and the armies fighting on the ninth floor.
Frank Q's gift
Frank gives Carl the ring in the Desperado Club after the collapse of his partnership with Maggie. He calls it revenge, although Carl initially sees a valuable piece of equipment rather than an attack. Frank says a jeweler on the preceding floor offered him 300,000 gold for it. He believes accepting such a prize can ruin its owner, as the dungeon's incentives have ruined him. His warning matters because the ring offers an immediate benefit even to someone who refuses to hunt other crawlers: simply wearing it raises all attributes by five percent. Carl can rationalize keeping it without committing to its killing skill.
The item's inspection text names the ring and describes Marked for Death. The wearer selects a target from a list within map range. Only a target at full health is eligible. Once a mark has formed, the target's death yields a permanent point in whichever attribute was that target's highest, regardless of who actually caused the death. The reward grows by one point after every three successful marked deaths. The cost begins before the reward: with a live mark, the wearer cannot heal. Damage, poison, or other ailments remain until the marked target dies. A target who escapes therefore turns the ring into an ongoing liability, even if the owner never confronts that person again.
The skill's rules vary by floor. Its initial description specifies a formation delay and cooldown on some floors, instant marks without a cooldown on the sixth, and the ability to hold multiple marks with a shorter cooldown on the ninth. Ordinarily it applies to crawlers. On the Scolopendra's Lair floors, including the sixth and ninth, it can also select non-dungeon-generated combatants. This exception later lets Carl turn a tool associated with killing fellow crawlers against invading hunters and Faction Wars personnel. The ring does not simply deal “divine damage”; its consequential effect is a trade of a target's death for attributes while exposing the wearer to a healing lock.
Mordecai is alarmed when he sees the ring on Carl's hand. Carl says he wants only its five-percent bonus, but Mordecai urges him to take it off or sell it. According to Mordecai, several such rings appear in a season, and their owners become early targets for the sixth-floor hunters. The same item that improves a crawler's odds of surviving a fight makes that crawler lucrative prey. Mordecai also explains the longer market: Faction Wars champions can become extraordinarily powerful by charging the ring, and armies seek rings that cannot simply be brought into the dungeon from outside. Frank's gift thus creates a threat before Carl ever chooses a mark.
From a bounty to a weapon against hunters
Carl still has the ring as the sixth-floor hunt approaches. He and Donut consider whether damage to the hunters' sales channels will lessen the pursuit. Carl doubts it. The ring remains useful to the hunters themselves, even if the ordinary route for selling crawler loot to faction buyers is disrupted. He also carries other coveted equipment, so keeping the ring adds to an existing target on his back. Its value is strategic as well as monetary: an army that secures it can grow a champion by exploiting the floor's permitted targets.
Carl's first deliberate use of Marked for Death occurs during the assault on the hunters' city. He puts the ring on, checks that the sixth floor allows immediate marks without a cooldown, and selects the hunter Chin'Dua. The interface identifies Chin'Dua's highest attribute as Dexterity and immediately imposes Left to Fester on Carl. Carl is already in a dangerous operation involving planted explosives and alerted hunters; the mark binds his ability to heal to the outcome of that operation. The choice is directed at a hunter rather than a crawler, using the floor-specific exception Frank's original description had disclosed.
Afterward, the ring's reward becomes visible in Carl's attributes and in its escalating benefit. Each additional successful mark moves him toward a larger return from the next death. The dungeon also treats his use of the ring as a distinct act: a reward box produces a spiderweb tattoo on his left elbow rather than an ordinary item. Carl later recognizes the design as connected to the Guild of Suffering. The mark on his body makes his participation visible even when the ring itself is in his inventory. Its symbolism is unwelcome to Donut, who sees the tattoos accumulating while Carl grows harsher under the pressure of the hunt.
Carl's use is opportunistic as well as direct. During a fight in Alucarda, he searches the ring's target menu to identify a priest whose visible name begins with Q. He marks the priest just before a berserking mantis kills him, then marks two more combatants amid the same clash. Carl does not have to deliver the killing blow to collect the reward. The three victims' highest attribute is Intelligence; the ring's benefit increases during the sequence, and Carl receives seven Intelligence points in all. The episode demonstrates the ninth-floor danger in miniature: a wearer who can recognize imminent deaths can harvest gains from a battle others are already fighting.
The ring's promise continues to tempt Carl after its reward has risen. Following another marked kill on the sixth floor, the system announces that its benefit has reached four attribute points per death. At the Butcher's Masquerade, he puts it on and marks Vrah once the chamber's protection fails. These actions are separated by very different battles, but the same constraint remains: a useful target must be eligible at the moment of selection, and a surviving mark leaves the wearer unable to recover normally. Carl cannot treat the ring as a passive improvement once he activates its skill.
Prepotente and Miriam Dom
Prepotente acquires another Ring of Divine Suffering on the sixth floor. Carl sees the spiderweb mark on his elbow and realizes he has already used it. Miriam Dom explains that she warned Prepotente against wearing it. In a fight involving repeated reflected magic, his ring behaves erratically and marks Miriam. Prepotente is then stunned and Fragile, with only a single point of health; Left to Fester prevents him from healing while she lives. The ring's cost becomes an immediate danger to someone who did not intentionally choose his target.
Miriam asks Carl and Donut to come before sunrise. She fears that trying to wake Prepotente while he is in this state could kill him, and she knows her own death will release the ring's condition. Carl refuses to kill her for a bounty. He nevertheless secretly puts on his own ring and marks her as dawn approaches, when her vampirism will cause her to die in sunlight. His mark qualifies for a ring reward from a death he does not cause, while he refuses the much larger bounty he could collect by killing her himself. The pairing exposes the ring's moral ambiguity more sharply than a battle with the sixth-floor hunters: its mechanics offer Carl a gain even as he rejects the easier, more lucrative violence available to him.
Once Donut wakes Prepotente, he removes his ring, briefly drops it, and then swallows it. Carl had wondered whether he might claim or combine it with his own ring, but Prepotente's action ends that possibility. The swallowed ring is part of his response to Miriam's death, not a new combat technique that the scene establishes. Carl and Donut witness a crawler refusing the object that had made his mother's final hours still more painful.
King Rust's ring and the ninth-floor choice
On the ninth floor, King Rust also wears a Ring of Divine Suffering. Tipid suggests the ring helps explain Rust's rapid increase in power, and a later account from Volteeg distinguishes its direct effect from an accompanying rise in levels: the ring is intended to raise attributes, but feeding it kills can also produce levels through combat. Rust's ownership shows why Mordecai linked these rings to Faction Wars champions. It also places a second copy within Carl's reach when Rust dies and Carl takes possession of his equipment.
Carl checks whether the two rings can be combined. He can wear only one at a time, and two rings cannot mark the same person on the ninth floor. Possessing both therefore does not simply double his own reward. Li Na asks for the spare. Carl is reluctant because she is already a formidable crawler and he fears the ring could intensify her violence. He consults Katia, Imani, Elle, and Donut. Imani objects; Donut asks him to give it to Li Na. Carl eventually does so. The transfer puts the ring with an ally who has her own combat style and judgment, rather than adding another copy to his inventory indefinitely.
The ninth floor offers Carl many apparent targets, yet he repeatedly encounters limits to marking them. Empress D'Nadia keeps her health just below full, denying him an eligible mark despite protective shields that stop his attacks from causing normal damage. After taking enemy mercenaries under his command, Carl realizes that their temporary conscript status would let him order them to stand still and kill them for easy gains. He removes his ring while they and his allies watch. This decision rejects an available use of the item, not an impossible one. The ring makes captured personnel into potential resources, and Carl recognizes what exploiting them would mean.
Carl later starts a mark on Lucia Mar but cancels it when a voice from within her asks him to wait for more information. Near the final fighting, he tries to use the ring's target list to locate enemies inside a crowded moving mass. The list shows allied and unaffiliated figures but not the enemies he expects, so he turns to another locating ability. He initially considers their health status as an explanation. Only later does he understand that Li Na has already marked the enemies and that the two rings cannot claim the same targets. The scene reveals both a practical limit on the skill and how much Li Na has done without Carl seeing it.
Li Na's mass marking produces enormous gains when many marked enemies die. It also leaves her vulnerable: Carl believes some targets, including Tagg and Fang, escaped. Until those marks are resolved, she cannot heal, while her chains consume small amounts of health. Her power increase and its unresolved cost occur together. Carl's earlier fear about giving her the ring is borne out in a specific way: it helps her dominate a battlefield, but each survivor can carry a dangerous condition beyond that battle.
As the ninth floor nears destruction, Carl faces one last opportunity to use his own ring against surviving enemies and raise his attributes dramatically. Seeing Li Na makes him reconsider the price of that path. He holds the ring up to Donut, who swallows it at his request. The act removes his copy from ordinary use at that point in the story. It follows repeated choices to withhold a mark when a target is vulnerable or when too little is known about them. The ring's final significance for Carl is therefore tied to a concrete decision: he gives up a powerful means of growth rather than turn the remaining combatants into a set of attribute rewards.
Tenth-floor confirmation — Book 8 spoiler
On the tenth floor, a system achievement refers back to Carl giving Donut the Ring of Divine Suffering to eat. This confirms that the ninth-floor act was recorded by the System; it does not establish whether the swallowed ring was destroyed, can be recovered, or remains usable. Carl's decision is clear, while the item's later physical state is not.
