The Flare Gun in use, firing both normal Flares and Blue Flares. Note how the Flares fired light up the surrounding environment.

The Flare Gun is a weapon that provides a ranged method of illuminating areas. It fires Flares, which provide light and stick to the blocks they hit. The Flare Gun is found randomly in Gold Chests underground.

Flares travel in a slight arc and stick to blocks (similar to Sticky Glowsticks), but have greater velocity and range. They are waterproof, and can be fired into and out of water. Once fired, Flares emit low-level, flickering, tinted light that lasts for 10 minutes. They stick to the blocks they impacted and will function underwater. Flares cannot be recovered once they burn out.

When held, the muzzle of the Flare Gun will continually emit a flare effect, as long as at least one Flare is in the player's inventory.

The Flare Gun cannot be reforged, and therefore cannot have modifiers.


  • The Flare Gun itself does not belong to any damage type, and its damage will not be affected by any factors, including those for all types of damage (like the Avenger Emblem or the Wrath buff). However, the Flares fired deal ranged damage.
  • The Flare Gun will equip when the player holds Quick Select with the Flare Gun and at least one Flare in their inventory, while also having their cursor out of Torch placement range, or when the player has no Torches or Glowsticks in their inventory.
  • The Flare Gun will not fulfill the spawn criteria for the Arms Dealer.


  • If playing in multiplayer, a player can use the Flare Gun much like a real-world flare gun, to signal other players for help. Due to its high range, it can shoot relatively far and can fairly easily reach the area of another player (barring obstacles).
  • The Flare Gun's shots will pierce targets. Since they inflict the On Fire!/Cursed Inferno debuff, the weapon can prove very useful for fighting off groups of enemies, such as during the Blood Moon, as well as keeping track of bosses and enemies in dark environments.
  • The Flare Gun can be especially useful against worm-like enemies (and bosses like the Eater of Worlds), or even the Brain of Cthulhu's Creeper minions. Surprisingly, the Flare Gun is also useful against Wyverns, being able to kill one with a single, well landed shot and a few seconds.
  • While mining downward, firing a Flare where the player is mining will allow it to fall with the player as they mine.
  • Due to the Flares' 10-minute duration, the Flare Gun can also be used to reach the 1,001 projectile spawn limit, making it an extremely useful setup tool before boss encounters by firing a thousand flares beforehand, subsequently preventing the boss from firing any projectiles while still allowing the player to fire projectiles themselves.
