The Face Monster is an enemy that can be found in the Crimson. Like other Crimson enemies, it drops Vertebra fairly often. New players should be cautious around it, as while it appears to be similar to the common Zombie, it is considerably more resistant to knockback, being able to do damage to a player even while being repeatedly attacked with most starting weapons. Unlike Zombies however, Face Monsters will not despawn during daytime.
The Face Monster is able to open doors regardless of whether there is currently a Blood Moon or not.
Even though it appears to be 4 tiles tall, it can fit through 3-tile spaces.
– According to the official game lore, the Face Monster once was a worshipper and/or sacrifice to the Crimson, raising it to the level of deity and giving it human sacrifices, which it accepted, turning them to mindless, loyal servants of the hivemind.
The Bestiary entry for the Face Monster: "It would be unwise to face off with one of these unfeeling, hungry mutations. Their mouths are large enough to devour all things."
