Upon entering a room with enemies, spawns a Black Locust that deals quadruple Isaac's damage, applied as two hits of double damage.
Notes[ | ]
The Locust will also spawn each time a wave starts in Boss Rush.
The Locust will not spawn each time a wave starts in Greed Mode.
If the player has exited the game, the Locust will spawn upon continuing from the main menu, allowing multiple locusts to spawn for the same room by repeatedly exiting.
