The Lost

The Lost is a familiar that fights on the player's side in combat. As a summonable ally, it represents a wandering or stray entity that has latched onto a cat's party, joining the fight wherever it can be useful.

Like all familiars in Mewgenics, The Lost acts independently each turn, targeting nearby enemies and providing an additional body on the battlefield. It can absorb hits that would otherwise fall on your cats, and its attacks contribute to clearing rooms even without direct player control.

Familiars with ambiguous origins like The Lost often have specific unlock conditions or item associations. Check what ability or trinket summons it — knowing the source helps you evaluate whether building toward it fits your current run's strategy.
