Urschleim is an optional end-game boss found within The Passage. When defeated, it marks a significant challenge in the late game.

Urschleim’s arena is located within The Passage, where it continuously moves in a set path. The Urschleim Scanner can be used to locate its position on the map.

To spawn Urschleim, players must find it naturally as it roams through the Passage. To respawn Urschleim, use a Primeval Slime Cell anywhere in the biome.

Urschleim slowly moves through the area, phasing through obstacles. During the fight, players must destroy its three glowing bulbs to expose its head, which becomes temporarily vulnerable before regenerating its defenses. As the bulbs are destroyed, Urschleim will increase in speed.
