The Forest Wiki

Burning is a condition that can affect the player, as well as wild animals, the environment, weapons, and even the cannibals themselves.


Burning is what happens whenever a valid entity makes contact with fire.

Things like Basic Fire, Fire Pit, flaming arrows, Molotovs and Flare Gun are all capable of causing the burning condition.

Most of the axes and other melee weapons can be combined with cloth to allow the player to set them on fire. This is achieved by pressing and holding L while the weapon is equipped. Swinging the weapon will reduce the burn time.

If the player gets caught on fire, he will flail and have a hard time attacking. To immediately remove the burning condition, the player can go deep enough into water to swim or be exposed to the rain.

Changes Between Difficulties[]

Burning will damage player's health or armor (depending if wearing any) in 4 "ticks", meaning that the player will receive damage 4 times after being ignited. On normal mode every tick will deal 4 damage, on hard mode 8 and on hard survival mode 20 damage. Player has to be very carefull near a fire, especially on the hard survival mode as it deals 80 damage in total.

Changes in Difficulty Modes by Ratios and Percentage
NMa.png= Normal HM.png = Hard HS.png= Hard Survival
Mechanic NMa.png HM.png HS.png Description HM.png to NMa.png HS.png to NMa.png HS.png to
Fire Damage Ratio 1 2 5 Damage Amount from Fire 100.00% 400.00% 150.00%

Fire Damage Creepy Mutant Ratio 1 0.35 0.35 Fire Damage Received by Creepies -65.00% -65.00% 0.00%

Fire Upgrade[]

Fire upgrades were originally added in v0.08 with cloth only upgrades. In update v0.32, players were able to add cloth and booze, which increases the benefits by up to 3x times the burn length and swing amount, however this was removed without notice or reason. You can combine a weapon and cloth for a temporary fire upgrade, which can make the upgraded item serve as a light source, a heat source to prevent cold damage, and a way to set enemies on fire. The weapons you can grant the temporary fire upgrade with cloth. Include the Modern Axe, Upgraded Stick, Crafted Club, Rusty Axe, Plane Axe, Club and Crafted Axe. When pressing and holding the hotkey to activate the lighter (default L), you can light the upgraded weapon or tool on fire.

IMPORTANT: If you apply 30 upgrades to any of these weapons, you will no longer be able to attach booze for a fire upgrade.

Cloth One of these
Club Upgraded

Fire Upgrade Guide[]


Fire Upgrade Mechanics[]

To attach fire upgrades to an applicable weapon (see the below table), right click on that weapon, this will place it on the crafting mat. Right click on cloth, then click the cogwheel to combine. If you wish to upgrade it further, right click on one booze, then click the cogwheel to combine.

  • It doesn’t matter how many times a weapon with cloth or cloth and booze gets extinguished. Extinguished meaning, going into water, standing in rain, or putting it into your inventory the timer will keep getting paused and it won't remove the upgrade.
  • Adding cloth to a weapon, once it is lit, adding cloth will restart the timer and swing count

Fire Upgrade Stats[]

  • Swinging weapons reduces the time they burn for. Each swing takes a percentage off the burn length, based on how long it burns for combined with how many swings it can make before being removed.

For example, a modern axe with cloth only will swing 7 times or burns for 110 seconds before being extinguished. Based on this information, 110 divided by 7% is 14.2 which is the percentage each swing will take off the burn time which is around 15 seconds in this case. If you add cloth and booze to the modern axe, it will swing 21 times or burns for 300 seconds. 300 divided by 21% is 4.7. Therefore, each swing removes 4.7% off the burn time. Which is around 14 seconds. This is around the same amount of time as cloth only but you have an extra 190 seconds to play with. Basically, the higher the percentage number, the worse it is. For example, the rusty axe with and without booze has the highest percentage. Making it the worst weapon for burning or fire upgrades.

Weapon Burn Length Seconds Swing Amount Swing % off burn time
Modern Axe 110 7 14.2%
Upgraded Stick 240 8 12.5%
Crafted Club 110 9 11.1%
Rusty Axe 80 3 33.3%
Plane Axe 50 4 25.0%
Crafted Axe 90 4 25.0%
Upgraded Rock * * *
  • The Upgraded Rock can accept fire upgrades though it will set you on fire. It is pointless to test the lengths for this reason.


  • When on fire, cannibals will take burning damage, as if the player was still hitting them with a weapon. They will also flail and not attack the player as they attempt to put the flames out, though their flailing can damage the player.
  • If a tree takes enough burning damage it will fall down.
  • Creates light, especially in dark caves.
  • Can be used as a way to obtain bones, if you dropped some deceased cannibals on a fire. After a few moments, the cannibal will disintegrate into bones for you to use for early armor.


  • While it deals low health damage, it burns off lizard skin at an alarming rate.
  • Causes a burning player to flinch as if hit, leaving them vulnerable to another attack if engaged in combat with cannibals.
  • Rarely, cannibals can throw flaming tennis balls at the player, which will result in the player burning.


It is wise to have your favorite axe wrapped in cloth just in case the player is ambushed by a group of cannibals, as merely running into a cannibal with a burning weapon is enough to ensure they are either killed by the fire or, at the very least, extremely weakened.
