Deer

Once the Stag spawns, it will move in a straight line toward the nearest player. Lanterns can be used to stun it, though it will recover faster after each stun. Initially, the Stag can be outrun, but the longer it pursues the player(s), the faster it becomes.
The deer also appears during cultist raids and stands next to the campfire. It flees if all the cultists are defeated or if the player gets too close. During this time, the deer does not appear anywhere else.

The Stag is an incredibly large and tall deer-like creature with an unnaturally large head, twitching ears, an elongated jaw, and cartoonishly large eyes. When hungry, the Stag's eyes change color from light blue to blood red.
It's a facultative bipedalist, usually standing on its hind legs but can move on all fours to quickly chase or escape players. Its front paws, or "hands" when standing on its hind legs, have four claws with which it attacks. The deer is primarily brown, with black hooves, antlers, and claws that range in color from brown to black.

This is a monstrous, bipedal, semi-anthropomorphic monster resembling a deer with clawed forepaws. At night, the Deer will pursue the player until they reach a safe zone (Camp) or inside the Cultist Fortress, dealing heavy damage.
The deer takes no damage from anything, rendering all weapons ineffective. However, the light from flashlights stuns it briefly, allowing the player(s) to escape. The deer will not enter the campfire's safe zone until the fire goes out, and will flee at dawn. If a player enters the safe zone while the deer is pursuing them, the deer will be stunned and flee.
