Flare Gun

The Flare Gun is a weapon that shoots Flares and Blue Flares, which provide light and stick to the blocks they impact, similar to Sticky Glowsticks. The Flare Gun deals very little damage but ignites enemies with the On Fire! debuff. It is intended primarily to provide a ranged method of illuminating an area.

Flares are fired in a slight arc and stick to walls, similar to Sticky Bombs and Sticky Glowsticks, but have much higher velocity and range. The muzzle of the gun displays sparks and emits light similar to that of Flares. Flares can be fired into and out of water.

Flare ammunition can be found in naturally-spawned chests, and bought from the Merchant for while a Flare Gun is in the player's inventory. Blue flares are also available from the Merchant.

Tips

 * The Flare Gun can be especially useful against the Brain of Cthulhu's first phase if used to ignite the eyes.
 * To conserve Flares in the early-game the spark effect from the Gun can be used as a light source while the Flare Gun is equipped.
 * If you go mining and need an automatic light source, simply shoot a flare down on the ground and keep mining. However, this does not work sideways, as the flares stick to blocks.

Trivia

 * The weapon is most likely a reference to the Flare Gun from Team Fortress 2.
