Slime Rain





Slime Rain is a minor event that consists of frequent spawns of Green, Blue and Purple Slime and rarely Pinky. It occurs randomly, signaling its beginning with the message "". Slime Rain continues until 150 slimes have been defeated, at which point King Slime will spawn. If King Slime has previously been defeated, he will spawn after only 75 slimes have been defeated. The event ends shortly after he is defeated or despawns. All slime spawns from the event will be continuously hostile, unlike naturally spawned slimes.

A Slime Rain can only occur if at least one player in the world has over 140 maximum health and 8 defense (except in Expert Mode, where it can occur before meeting the criteria – with a significantly decreased chance). Given those criteria, a Slime Rain has an approximate 4.9% of chance of occurring in a pre-Hardmode world per day (approx. 3.3% in Hardmode). If King Slime has not been killed yet, the probability for a Slime Rain to occur is doubled.

While a Slime Rain is active, Green, Blue, and Purple Slimes will appear to fall in the background. The event can last anywhere from 9 to 15 in-game hours. If the player fails to defeat 150 / 75 slimes by the end of the Slime Rain, the message "" will appear and the Slime Rain will end naturally without King Slime spawning. The event will not end if the player leaves the world, that even resets the time of the event.

Tips

 * The event can be avoided entirely by staying indoors or underground, as it can end without any player interaction after a certain amount of time has passed.
 * The high spawn rate of Slimes during a Slime Rain, including Pinky, greatly facilitates farming for Gel, Pink Gel, Slime Staff, and the Slimes' Banners. King Slime will also offer loot that is useful at the beginning of the game.
 * An enclosed shelter with a 1×1 hole in the wall will allow the player to fire arrows and use Yoyos from relative safety. However, once King Slime spawns, it is advised to leave, as he can teleport into the shelter and trap the player.
 * The spawn rate can be increased with a Water Candle and Battle Potion. Similarly, it can be decreased with Sunflowers, a Calming Potion, and Peace Candles.

Trivia

 * The Slime Rain effect in the background can be seen before the event is announced if the player goes up high enough.
 * Some slimes appear to spawn in the air above the player which results in them falling from the sky, giving the term "rain" a literal meaning.
 * The Slime Rain is one of two events in Terraria that cannot be summoned via the use of an item, the other being the Martian Madness.
