Slime Time: When the Moon Silences the Bounce

Slimes, those gelatinous cubes of joy (or annoyance, depending on your perspective), are a staple of Minecraft. But their spawning habits aren’t always straightforward. One critical factor influencing their appearance, particularly in swamp biomes, is the phase of the moon. So, the definitive answer: Slimes never spawn during a new moon in swamp biomes. Read on to dive deep into slime spawning mechanics!

Understanding Slime Spawning Mechanics

Slimes, unlike many other mobs, have two primary spawning conditions:

• Underground Slime Chunks: These are specific chunks (16×16 blocks) that can spawn slimes at any light level below Y=40. The moon phase is irrelevant in these chunks.

• Swamp Biomes: Slimes can spawn on the surface of swamp and mangrove swamp biomes between Y=51 and Y=69, with a light level of 7 or less. This is where the moon phase becomes crucial. The fuller the moon, the more likely slimes are to spawn. A new moon effectively shuts down slime spawning in these biomes.

This relationship with the moon’s phases is unique and makes slime hunting a lunar-dependent activity.

Factors Influencing Slime Spawning

While the absence of spawning on new moons is the core of our discussion, understanding other factors is crucial for effective slime farming and management.

Light Level

As mentioned earlier, light level plays a role in swamp biomes. The light level must be 7 or less for slimes to spawn there. This means that daylight or too many torches will prevent spawning. Interestingly, as of version 1.19.81 as well as 1.20.0.22 Preview, slimes only appear to spawn in swamps with a block light level of 0, and don’t spawn with block light levels 1-7. This makes things even more challenging.

Biomes

Slimes only spawn in swamps on the surface. Underground, they are restricted to specific slime chunks, regardless of the biome. The Mushroom Fields biome is the only biome where they never spawn underground.

Proximity to Players

Like most hostile mobs, slimes adhere to the standard mob spawning rules.

• They won’t spawn within 24 blocks (spherical) of any player.
• They will begin to despawn over time if no player is within 32 blocks.
• They instantly despawn if no player is within the despawn radius (128 blocks in Java Edition, 44 to 128 blocks in Bedrock Edition depending on simulation distance).

Other Mobs

Slimes are shy! The game’s spawning algorithm has a limited number of mob slots available. If other mobs are present in the area, they can effectively block slimes from spawning. Clearing out the caves around a slime chunk will increase the chances of slimes appearing.

Maximizing Slime Spawns

To effectively farm slimes, consider these strategies:

1. Locate Slime Chunks: Use online tools like Chunkbase to find slime chunks in your world. While Chunkbase is generally accurate for biome locations, remember that specific structure placements are not always perfect. Use the F3+G key combination in-game to show chunk boundaries.

2. Prepare the Slime Chunk: Dig out a large area below Y=40 within the slime chunk. Flatten the floor and light it up to prevent other mobs from spawning. Remember that slimes spawn regardless of light level within slime chunks.

3. Optimize Swamp Spawns: Find a swamp and eliminate all light sources to maintain a light level of 7 or less. Wait for a full moon for the highest spawn rates. Clear the swamp area to improve spawn rates.

4. Create a Slime Farm: Design a farm that automatically collects and kills slimes for efficient slimeball gathering.

5. The Night Slime: If you are using mods, one to look for is the Night Slime. This slime spawns at night, and is especially present during a full moon.

Frequently Asked Questions (FAQs)

1. Do slimes spawn on every moon phase?

No. While they spawn more frequently on fuller moons, they never spawn on a new moon in swamp biomes. In slime chunks, the moon phase has no impact.

2. Can slimes spawn during a solar eclipse?

The provided information does not describe if slimes spawn during a solar eclipse.

3. Can slimes spawn in every biome?

No. Slimes only spawn in swamp and mangrove swamp biomes on the surface. Underground, they spawn exclusively in slime chunks, found in any biome except mushroom fields.

4. How rare is it for slimes to spawn?

They are relatively rare. Slime chunks only make up approximately 10% of all chunks, and surface spawning in swamps depends on light level and moon phase.

5. Do slimes spawn more on a full moon?

Yes! Slimes spawn most frequently during a full moon in swamp biomes.

6. Why won’t slimes spawn in my swamp?

Several reasons: the light level might be too high (needs to be 7 or less and at a level of 0 in recent releases), it could be a new moon, other mobs might be taking up spawn slots, or you might be too close (within 24 blocks).

7. How do I make sure only slimes spawn?

Clear out caves and tunnels around your chosen area, place torches to prevent other mobs from spawning in those areas, and eliminate spawners.

8. Do pet slimes Respawn?

This depends on the context. The article states that if you’ve managed to free slime NPCs, they’ll be able to respawn as long as you have valid houses for them.

9. Do slimes spawn every night?

Slimes spawn naturally at nighttime in swamp biomes, but the frequency is significantly influenced by the moon phase. They are most plentiful during a full moon.

10. Do slimes only spawn at night?

In swamp biomes, yes, slimes primarily spawn at night. Underground, in slime chunks, they spawn at any time.

11. Do slimes spawn on peaceful difficulty?

No, slimes do not spawn on peaceful difficulty. You can obtain slimeballs through trading or from baby pandas sneezing.

12. What biomes can slimes not spawn in?

Mushroom Fields are the only biome in which slimes never spawn.

13. How do I stop slimes from spawning in my cave?

Cover the floor with slabs, glass, or other blocks that mobs cannot spawn on.

14. How tall of a space do slimes need to spawn?

The provided document doesn’t state the height of space needed for slimes to spawn, but states that slimes can spawn in slime chunks when Y < 40, and in swamp biomes between Y=51 and Y=69.

15. What is the moon cycle for slimes in Minecraft?

The number of slimes that spawn in swamps is proportional to the moon’s fullness. Most during a full moon and none during a new moon.

By understanding these factors, you can significantly increase your slimeball production and dominate the sticky piston market!
