Can You Summon Slime Rain in Terraria? A Comprehensive Guide

The short and direct answer is: no, you cannot directly summon a Slime Rain in Terraria through the use of an item or specific action. Unlike many other events and bosses in the game, the Slime Rain is a random event that is primarily triggered by chance. This makes it a unique occurrence that players must be prepared to encounter, rather than something they can plan for. This article will delve into the mechanics of Slime Rain, its features, and other related aspects that you, as a Terraria player, might find useful.

The Unpredictable Nature of Slime Rain

The Slime Rain is one of the few combat-focused events in Terraria that cannot be manually summoned. It is an event where numerous slimes seemingly fall from the sky, hence the name. This makes for an interesting and sometimes chaotic experience, particularly for newer players. It’s a situation where you can be going about your business, and suddenly, gelatinous creatures begin raining down.

How Slime Rain Begins

The onset of a Slime Rain is largely dependent on random chance. Immediately after world generation, the chance of rain occurring is initially locked at a base percentage (18.2%), which doesn’t fluctuate for a period between 2 minutes 24 seconds and 24 minutes. However, this chance increases by a small amount per tick (1 in 86400) whenever a player kills a regular Ladybug, or uses one while fishing.

The event itself is predicated on specific player conditions. A Slime Rain can only occur if at least one player in the world has over 140 health (7 hearts) and 8 defense. This requirement makes it unlikely to occur in the very early stages of the game, providing new players with some time to prepare for such an event.

What Happens During a Slime Rain?

Once triggered, the Slime Rain will continue until a specific number of slimes have been defeated. Initially, the event continues until 150 slimes have been killed. After 150 slimes are defeated, King Slime will spawn. Should you have defeated King Slime on that world in the past, he will spawn after only 75 slimes are defeated during the event. The event ends soon after King Slime is defeated or despawns.

It’s important to note that slimes killed by players, lava, traps, and even summoned minions all count toward the total. This gives players multiple ways to handle the situation and expedite the arrival of King Slime, who serves as the culminating encounter.

Slime Rain Rarity

The odds of a Slime Rain occurring are around 4.9% per day in a pre-Hardmode world and 3.3% per day in a Hardmode world. While these percentages might seem small, they do mean that the event is fairly common over the long term, given enough in-game days have passed. This randomness adds to the game’s challenge and keeps the experience varied. It encourages you to have contingency plans for the sudden influx of slimes.

Frequently Asked Questions (FAQs) About Slime Rain

To further clarify this unique Terraria event, here are 15 frequently asked questions:

Can King Slime spawn during Slime Rain? Yes, King Slime will spawn once 150 slimes have been defeated during a Slime Rain event (75 if he has been defeated before). This is the primary way he spawns without using a summoning item.
Is there an achievement related to Slime Rain? Yes, there’s an achievement called “Survive the slime rain,” which requires the player to complete a Slime Rain event by killing 150 slimes and then defeating King Slime.
Where do the slimes come from during a Slime Rain? The game treats it as though they are spawning in the air above the player, and then fall from the sky. This gives the term “rain” a literal meaning.
Are there any special types of slimes that spawn during the Slime Rain? While the majority of slimes are standard types, the sheer volume of slimes that appear makes the event a challenging encounter on its own.
Can I use a Slime Crown to spawn King Slime during a Slime Rain? You can use a Slime Crown at any time to summon King Slime, even during a Slime Rain, but it is not needed as the event will summon him once the required number of slimes are defeated. This does mean you can spawn King Slime while the Slime Rain is still in progress, in effect fighting two bosses in one encounter.
Is there any way to increase the chance of a Slime Rain besides killing Ladybugs? No, killing Ladybugs or using them in fishing is the only way to influence the chance of Slime Rain occurring.
Does the Slime Rain event only happen in Pre-Hardmode? No, Slime Rain can occur in both Pre-Hardmode and Hardmode, though the odds are slightly lower in Hardmode.
Can multiple Slime Rains happen in the same game day? It is theoretically possible, though highly improbable, for multiple Slime Rains to occur within the same in-game day, though it’s not advised to pursue triggering another if you already have completed one that day.
What happens if I die during a Slime Rain? Dying during a Slime Rain doesn’t stop the event. The slimes will continue to spawn, and the event will progress. You will have to come back and complete it if you were working towards King Slime’s spawn.
Does the time of day affect the chance of a Slime Rain? No, the Slime Rain is a purely random event that can happen at any time of the day. It is not affected by the time of day or the lunar cycle.
Can the Slime Rain trigger while other events are active? Yes, Slime Rains can occur alongside other events, though there are certain events that can stop other events, but the Slime Rain is not one of these.
What do I do if I can’t survive the Slime Rain? The best action is to make a safe area or a bunker out of blocks, and to take the slimes in smaller numbers instead of as a group. King Slime won’t be spawned until 150 slimes are defeated, giving you a chance to improve your gear or strategy.
Are there any unique items that drop from Slimes during a Slime Rain? No, the slimes that spawn during a Slime Rain drop normal slime items and no special drops specific to the event.
Does King Slime despawn if the player moves too far away? Yes, like most bosses, King Slime will despawn if the player moves too far away from him.
Does Slime Rain influence any other game mechanics? Besides the fact that a Slime Rain is often a pre-cursor to King Slime’s natural spawn, the event does not have any unique interaction with other game features.

Conclusion

While you can’t directly summon a Slime Rain, understanding its mechanics allows you to anticipate and strategize around it. This random event is a unique part of Terraria’s charm, providing an unexpected challenge and a path to summoning King Slime. Keep an eye out for falling slimes, prepare your defenses, and get ready to earn that “Survive the slime rain” achievement. Happy gaming!
