The Deer cannot be killed. Use a charged flashlight for a brief stun and return to a lit safe zone.

Quick answer
The Deer is the game's main nighttime antagonist. It chases players outside the campfire's safe zone, cannot be damaged by weapons, and can briefly be stunned by flashlight light. That changes the decision: prepare an escape route rather than a fight.
Where the safe zone helps
A lit Campfire repels The Deer and several other monsters. As the fire levels up, its safe zone and the visible map expand. Keep fuel at camp before leaving on a long supply or rescue run. If the fire burns out, the map becomes unavailable and The Deer can reach camp.
What to do when The Deer spots you
- Use light for a gap
A charged Flashlight briefly stuns The Deer. Its battery is limited and can be recharged near the campfire or fireflies.
- Move toward safety
Use the stun to get back into the lit campfire radius or another safe location. A weapon will not finish the encounter because The Deer has no killable health pool.
- Check the fire afterward
Relight or refuel it if needed before another player leaves camp.
One important exception
The campfire does not stop cultists from entering camp. Its protection against The Deer should not be mistaken for total base defense.
