Bone Marrow

One of the best sustain trinkets in the game — the wearer fully heals at the end of every battle, no healing items or abilities required. This effectively eliminates inter-battle healing costs for one cat, making it especially valuable during long runs with back-to-back fights. Heat Wave status can block the heal, so watch for lingering debuffs when you need the recovery most. Part of the Bone and Meat sets.

Full post-battle healing means you can let this cat soak more damage during fights without worrying about long-term attrition. It removes the need to carry healing consumables for that slot and frees up party resource budget for other purposes. The Heat Wave exception is the main caveat — if an enemy or environmental effect inflicts Heat Wave and it persists past the battle end, Bone Marrow doesn't trigger. Always clear debuffs before relying on the end-of-battle heal.

Best on a durable frontline cat that takes consistent damage across fights — a tank or high-health brawler who would otherwise chew through your healing supply. Pairing with Bone or Meat set items adds further benefits and reinforces the sustain-focused build. In runs where healing items are scarce or you've committed them to other party members, Bone Marrow essentially makes one cat self-sufficient, a major resource advantage in extended dungeon floors.
