Rainbow Slime

The Rainbow Slime is a rare Hardmode slime that spawns in The Hallow ( on non-Hallowed blocks) while it is raining. It constantly changes color, as do the Rainbow Bricks it drops.

Tips

 * One way to encounter Rainbow Slimes in the Hallowed forest biome is to set up a Water Candle inside the edge of the Hallow 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 the 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. Setting up a large number of platforms may thus increase the likelihood of discovering one. The platforms must be somewhere off-screen, as enemies normally cannot spawn on the same screen as the player.

Trivia

 * The Rainbow Slime is the largest slime (excluding King Slime and ) and deals the most damage out of all slimes (including King Slime and Queen Slime).
 * If the player shoots a Rainbow Slime with a, it will fade to a gray color, but will return after the effect is over.
