A crawler-killer skill that marks a full-health crawler for a permanent stat gain on their death — but blocks all healing until they die.
Marked for Death is one of the dungeon's most infamous skills, imparted by the Night Wyrm's Ring of Divine Suffering that Frank Q hands Carl on The Iron Tangle. The wielder can mark any crawler at 100% health; after a 30-second set (instant on floor six), the marked crawler's death — by any cause — grants a permanent +1 to their highest stat, scaling up per three kills. The terrible catch: once a mark is set, the marker cannot heal at all, suffering every injury and pain until the prey dies, so a mark that escapes is a death sentence.
Cooldowns and mark-limits vary by floor (five hours here on floor four; none, and instant, on floor six; up to unlimited simultaneous marks on floor nine). It is the mechanic behind the whole Frank-and-Maggie tragedy: Yvette marked Carl, and after the ambush failed Maggie My could not heal her own blast wounds while Carl lived — so she killed her marked-linked daughter to end the agony.
An interface skill: a selectable list of full-health crawlers, a 30-second mark timer, and a healing-lockout status while a mark is live.
The Night Wyrm's Ring's core skill — the murderous, self-punishing mechanic at the heart of the Frank/Maggie/Yvette tragedy.
