Fötusjar

The Fotusjar is a glass-encased enemy from The Future chapter: a fetus preserved in a jar that attacks with frenzied Fury Swipes from within its container. With 6 HP, it is one of the frailer enemies in the chapter, but its multi-hit melee attack can deal surprising burst damage to cats caught adjacent to it. It is immune to magic and all status effects, making debuff-based strategies completely ineffective against it.

When the Fotusjar is killed, its glass container shatters, releasing Der Fotus as a separate enemy while simultaneously creating a water tile on its death spot and converting adjacent tiles into glass. This terrain transformation adds environmental hazards to the fight: glass tiles can shatter under weight, and the water tile can interact with electric or ice-based abilities. The released Der Fotus is a more mobile version that fights independently of its former container.

Because the Fotusjar spawns a new enemy and creates terrain hazards on death, position your cats away from the kill zone when finishing it off. Ranged attacks let you destroy it from a safe distance, avoiding both the glass tile conversion and the immediate threat of Der Fotus emerging next to your cats. In encounters with multiple Fotusjars, stagger your kills to avoid creating overlapping hazard zones across the battlefield.
