The Rainbow Gun is a Hardmode, post-Plantera magic weapon. It launches a rainbow beam that travels in a straight line for a short distance before curving downwards. The rainbow persists for 20 seconds or until another rainbow is fired. Enemies touching it take damage repeatedly, approximately five times per second. The Rainbow Gun is found in the Dungeon's Hallowed Chest, which must be unlocked with a Hallowed Key.

Its best modifier is Mythical.

Physics[edit | edit source]

  • Fired horizontally, the beam will travel straight for approximately 35 tiles before curving.
  • Fired 45 degrees, diagonally, the beam will travel approximately 4 tiles before curving.
  • Fired at a perfect 90-degree angle up or down, the beam will travel straight for 1491 tiles and end abruptly after that.[1]

Notes[edit | edit source]

  • The Rainbow Gun produces minuscule knockback for each of its rapid hits, which tends to freeze enemies within its field. This is similar to the Vilethorn's effect, though the Rainbow Gun does not travel through blocks.
  • When fading, the beam will not fade all at once; but instead along its length similarly to the way it was formed. Firing another beam will cause the first to instantly disappear without this "fading" effect.
  • It can be fired through one tile-wide gaps in walls, floors and ceilings, and will fire through solid one-block-thick walls at certain angles, even without standing against the blocks to be penetrated.

Tips[edit | edit source]

  • The Rainbow Gun can be considered a powerful endgame weapon. It pierces infinitely and delivers its 45 damage repeatedly and rapidly without having to re-fire for 20 seconds. Clusters of unlimited enemies, even post-Plantera Dungeon enemies (with the exception of Paladin and bosses), can be defeated all at once with a single firing.
  • This weapon will pierce infinitely until it fades. Therefore, it is a great weapon against enemies with multiple segments, especially worm-like enemies such as The Destroyer. It will hit each section simultaneously, inflicting tremendous damage. Because of this, it is potentially possible to defeat the Eater of Worlds or even The Destroyer with a single shot, if the player has appropriate gear and has made other preparations.
  • The Rainbow Gun is also exceptionally powerful against walking creatures or teleporting creatures. In the Hardmode post-Plantera Dungeon, while aiming towards the only passage leading into the room, the player can lay down a rainbow that eliminates every enemy that enters besides the occasional Cursed Skull or Paladin.
  • For the same reasons, the weapon is exceptionally potent against invasions.
  • The Rainbow Gun is great against the Celestial PillarsDesktop VersionConsole VersionMobile Version and for the same reason as with the Nimbus Rod, it allows for long-distanced healing (if the pillar is targetable) when equipping the Spectre armor with the hood.

Trivia[edit | edit source]

  • The rainbow makes a faint light that is synchronized with other rainbow items such as the Disco Ball and Rainbow Bricks.

History[edit | edit source]

  • Desktop 1.3.4.1: Fixed a glitch that allowed players to obtain the Rainbow Gun Pre-Hardmode on a world with the seed 1423781313 (small, Crimson, Expert mode). On the right side of the Dungeon, the game tried to place a Hallowed Chest and a wooden Chest in the same place, and the loot from the Hallowed Chest appeared in the Wooden Chest.
  • Desktop 1.3.0.1:
    • Rainbow duration increased from 10 to 20 seconds.
    • Knockback increased from 2 to 2.5.
