Blood Moons are rare events that can occur on non-boss night on the player's farm. There are currently three different variants of Blood Moons, each one categorized by it's distinct look and enemy variety. It is unknown if certain Blood Moons are more likely to appear over others.

Moon Pursuer[edit | edit source]
If the player is outside of their farm when a Blood Moon occurs, the Moon Pursuer will fall from the sky and chase the player. It is a large, unkillable entity featuring several giant teeth, continuously opening and snapping shut it's giant maw. Regardless of which area the player touches, the Moon Pursuer will always deal contact damage. The Moon Pursuer will only disappear when the player has returned to their farm. However, the Moon Pursuer will reappear once more if the player again attempts to leave the farm, essentially locking the player onto their farm for the remainder of the Blood Moon event.
