Void

Void is a fix for a problem rather than a monster: it brings a lagging player back to the group. Nobody knows what it looks like, since it simply appears as a black void; when crucified it shows as a large rounded cloud of black smoke. It exists in The Hotel and The Mines, and was added on January 28, 2023.

What it does

The game only keeps a limited number of rooms open at once: 5 from the start of the floor, 4 once Door 64 is opened and 3 after Door 80. If you are still in a room that is about to unload, Void closes the exit door, dims the room until it fades to black, teleports you with a bright flash to the most recently loaded room and then deals 20 to 40 random damage. It usually happens in multiplayer when someone falls several rooms behind. It can also happen solo if an entity that opens doors, like Rush, goes through.

Staying safe

Players with low health should stay with the group, because Void can kill. A Crucifix cancels its damage but you still get teleported. It also works as a failsafe with no damage, for example when the teleport in or out of Halt's room fails, or when you stay in The Library after Guiding Light closes Door 51. If Screech is near when Void immobilizes you, it can skip its warning and hit for extra damage, so look around.
