Liver

An uncommon Guts set head armor found in The Core, also obtainable from the Dyingfetus event. Grants +2 Constitution and +1 Health Regen — a straightforward durability boost that improves both your HP ceiling and passive recovery. Part of the organ-themed Guts set alongside the Heart. Reliable passive sustain for any build that benefits from stacking CON and Regen.

+2 CON is a meaningful HP pool increase that scales naturally with tanky builds, while the +1 Health Regen provides baseline passive recovery each turn. The Guts set pairs Liver (head) with Heart (neck) for a total of +4 CON and +2 Health Regen across two slots, making it a strong defensive foundation. As a head armor with no Shield value, the Liver trades raw damage absorption for sustained HP recovery.

Best for Tank, Fighter, or any constitution-stacking build that wants long-term sustain over burst defense. Wearing it alongside Heart completes the Guts set and gives a solid stat profile for endurance fights. The Dyingfetus event acquisition route means you can plan for this drop if you encounter the event — worth targeting for CON-dependent builds.
