what light level do slimes spawn
Where to Find Slimes. In Minecraft, you can find slimes in the Swampland biome in light levels of 8 or less. Slimes will spawn in the dark, usually at night. Once a slime has spawned in the dark, it can survive in the daylight. If you are having trouble finding a slime, you can summon a slime using a cheat.
1 Slime can also be found in swamp biomes when it's nighttime (dark). This is for those who have the Pretty Scary Update of Minecraft. They spawn more with a full moon and not at all with a new moon.  Slimes can be found below level 40 in the Xbox version as well, since TU8.
