Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
⬇ DownloadSlimes are unique mobs that spawn only under certain conditions. Unless the biome you are in is a swamp biome, slime mobs will only spawn if the chunk is a predetermined slime chunk. Slime Utils Mod is here with some features that will allow you to find slime chunks. This is done using the /slime commands. Furthermore, the mod adds a new gamerule that allows you to alter what percentage of chunks in your world are slime chunks.
Features:
- /slime: Check if the chunk you are in is a slime chunk.
- /gamerule slimeChunkPercentage : Set the percentage of slime chunks. Default is 10.
