The Rainbow Slime is a rare Hardmode slime that spawns in The Hallow (Console and Old-gen console versions 3DS version on non-hallowed blocks) while it is raining. It constantly changes color, as do the Rainbow Bricks it drops.

Just like many other slimes, Rainbow Slimes will be passive towards any player with the Royal Gel accessory equipped.

It is one of the few entities that can be detected by the Lifeform AnalyzerDesktop, Console, and Mobile versions or its upgrades.


  • Rainbow Slimes can also spawn on Hallowed blocks that are submerged in water.
  • It deals the most damage out of all the slimes, not including King Slime and Queen Slime.
  • It is the largest ordinary (non-boss) slime.
  • There is a greater likelihood that it will spawn when it rains and there is a Blood Moon currently active.
  • 3DS version If the player shoots a Rainbow Slime with a Heart Arrow, it will fade to a gray color, but will return after the effect is over.

  • Console and Old-gen console versions 3DS version One way to encounter Rainbow Slimes in the hallowed forest biome is to set up a Water Candle inside the edge of the hallowed biome and wait at this location until it rains, allowing enemies to spawn off screen on non-hallowed blocks. Alternatively, hallowed blocks can be covered with snow or bricks of some kind to allow Rainbow Slimes to spawn, though this will prevent other Hallow enemies from spawning.
  • Another way is to place about 200 blocks of Pearlstone, Pearlsand, or pink ice above forest surface and wait for the rain with the Water Candle and Battle Potion ready. To avoid Forest transformation to Hallow, proper spacing is required.
  • Rainbow Slimes are also able to spawn on platforms, meaning that if you make a large setup using them, you have a high likelihood of discovering one.
    • The platforms must be somewhere offscreen, as enemies normally cannot spawn on the same screen as the player.


  • The BestiaryBestiary entry for the Rainbow Slime: "These blessing-infused gelatin menaces glow vibrantly in a rainbow of hues. As a result, they require a constant liquid intake."
