The 信号枪 is a 远程武器 that provides a ranged method of illuminating areas. It fires Flares and Blue Flares, which provide light and stick to the 物块s they hit. They also deal minimal damage, and inflict the 着火了！ 减益. The Flare Gun is found randomly in 金箱s underground.
Flares travel in a slight arc and stick to 物块 (similar to 粘性荧光棒s), but have greater velocity and range. They are waterproof, and can be fired into and out of 水. Once fired, Flares emit low-level, flickering, tinted light (red or blue, depending on the type fired) 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 one Flare is in the player's inventory.
The Flare Gun cannot obtain 修饰语s.
Flares are used as 弹药 for the Flare Gun. There are two variants that work identically, but do not stack together: Flares (red) and Blue Flares. They can be purchased from the 商人 for 7 each, while a Flare Gun is in the player's inventory. 25-50 Red Flares are also found in 金箱s that contains a Flare Gun.
- The Flare Gun will equip when the player holds
- Similar to Glowsticks, Flares do not actually become 放置 as 物块, and are not saved with the world.
- The Flare Gun will not fulfill the spawn criteria for the 军火商.
- The damage type of Flare Gun does not belong to any one, and will not be affected by any factors, including those for all types of damage (like Avenger Emblem or Wrath buff). However, the Flare and Blue Flare deal 远程伤害.
- The Flare Gun's shots will pierce targets. Combined with the 着火了！ debuff, it can prove very useful for fighting off pre-hardmode hordes, such as the 血月, as well as keeping track of bosses and monsters in dark environments.
- The Flare Gun can be especially useful against the 克苏鲁之脑's 飞眼怪 minions and worm-like monsters and bosses like the 世界吞噬怪.
- While mining downward, fire a Flare down on the ground and keep mining. The Flare will fall with you as you mine.
- Farming fishing bait is made trivial by shooting the ground under you with the Flare Gun while wearing 花靴 and auto-swinging a 虫网. Expect around 25-40+ 蚜虫 drops per flare duration using this method. This method is significantly faster than using the 金虫网 and Flower Boots combination alone as the flare will break plants far faster than a swing of the Golden Bug Net (somewhere in the range of 10 to 1 rate difference it seems).
- If in danger or a tight spot, a player can use the Flare Gun and shoot it in the area of another player. Due to its high range it can shoot relatively far and can be used to signal other players for help when playing 多人模式. This is what Flare Guns are used for in real life.
