The Mantis is a Hardmode enemy which spawns on the Surface Astral Infection biome. It chases the player on the ground, gaining speed if continuously running in one direction, slowing down when turning around, and hopping if it encounters a gap in the ground or a change in elevation. If the player is on the ground and close enough, it briefly stops and fires a short-ranged spinning scythe projectile at them.


  • The Mantis' projectile is a reference to the projectiles fired by the Mantis Lords boss and Mantis Petra enemy in the game Hollow Knight.
