Slime Rain

 “Slime is falling from the sky!” 

King Slime spawning during Slime Rain. Note the falling slimes in the background.

Slime Rain is a minor event that consists of frequent spawns of Green, Blue, and Purple Slimes, and rarely Pinky. During the event, all slimes spawned will exhibit hostile behavior towards the player when spawned, unlike naturally spawned slimes; Green, Blue, and Purple Slimes will also appear falling in the background. Slime Rain occurs randomly, signaling its beginning with the status message "Slime is falling from the sky!". During the event, the King Slime will spawn after 150 slimes have been defeated. If King Slime has previously been defeated in the world, he will spawn after only 75 slimes have been defeated.

Slime Rain will not end if the player leaves the world. However, defeating the King Slime during the event immediately ends it. If the player fails to defeat 150 / 75 slimes by the end of the Slime Rain, the Slime Rain will end naturally without King Slime spawning. The status message "Slime has stopped falling from the sky." will appear when the event ends.

Details

The duration of a Slime Rain varies with game mode:

• In singleplayer, a Slime Rain can last anywhere from 9 minutes to 14 minutes 59 seconds.
• In multiplayer, a Slime Rain will always last for 15 minutes.

A Slime Rain cannot be initiated manually, so in order for it to occur, the following criteria must be met:

• At least one player in the world has more than 140 maximum health and more than 8 defense (except in Expert Mode, where it can occur before meeting these criteria – albeit with a significantly decreased chance).
• None of the following events are active: Rain, Lantern Night, Blood Moon, Solar Eclipse, Frost and Pumpkin Moons, Goblin Army, Frost Legion, Pirate Invasion, Martian Madness, and Old One's Army.

Additionally:

• Slime Rain will never occur in Don't dig up or Get fixed boi worlds.
• When a world is newly generated, Slime Rain will not occur within a period of time, which is randomly determined between 24 minutes and 48 minutes.
• In singleplayer, after a Slime Rain ends, another Slime Rain will not occur within a period of time, which is randomly determined between 84 minutes to 179 minutes 59 seconds.
  • In multiplayer, no restriction is applied. Another Slime Rain may occur immediately after a Slime Rain ends.

A Slime Rain can only occur between 4:30 AM and 12:00 PM. It has a 1/225,000 chance of occurring each tick during this time, resulting in a chance of 3/25 (12%) each day. The chance is decreased in Hardmode, if King Slime has already been defeated, and for Expert Mode players that do not meet the criteria:

Chance for Slime Rain per day (Pre-Hardmode)

	King Slime
	not defeated	defeated
Classic Mode or criteria met	3/25 (12%)	3/50 (6%)
Criteria not met	3/125 (2.4%)	3/250 (1.2%)

Chance for Slime Rain per day (Hardmode)

	King Slime
	not defeated	defeated
Classic Mode or criteria met	2/25 (8%)	1/25 (4%)
Criteria not met	2/125 (1.6%)	1/125 (0.8%)

Notes

• The Slime Rain can occur while a boss is alive.
• Only Blue Slimes (including those spawned from a Slime Statue) and any of its variants that share the primary NPC ID value of 1 count toward the event's kill count: Jungle Slime, Yellow Slime, Red Slime, Purple Slime, Black Slime, Baby Slime, Pinky, and Green Slime.

• Slimes can be killed in any way, including lava, traps, and friendly NPC attacks.

• It is possible to end the event by manually summoning the King Slime (via Slime Crown) and killing it.
• If the King Slime spawned by the Slime Rain despawned, the event will continue, and killing enough slimes before the event ends can cause the King Slime to spawn again. However, the required kill count is increased after the first King Slime has spawned: the player have to kill 225 slimes (or 102 slimes if King Slimes has been defeated previously) for subsequent King Slimes to spawn.
• The Sticky Situation achievement will not be awarded if the event ends without King Slime having been defeated.
• If the player is in a biome that features special variants of slimes, those slimes will not rain from the sky and their normal spawn rates will not be affected.
• Slimes spawned by the Slime Rain are not affected by the enemy spawn rate slider in Journey Mode.

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, bullets, 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.
• Making an arena with at least 2 layers is helpful, as the slimes would fall on the top to be easily farmed by the player. Once King Slime spawns, the player could go under the arena, in which the slimes would still be falling on the top of the arena, so they do not get in the way of the King Slime fight.

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 combat-focused events in Terraria that cannot be summoned via the use of an item, the other being the Martian Madness.
