DatapacksJava
Nightmare King Grimm
Java data pack listed for Minecraft 26.x. Downloads from the MC Java Mods app on Android.
⬇ Download on Modrinth
This datapack allows you to play as Nightmare King Grimm. Just run /function grimm:nightmareking.
Simulates NKG's fire bats, balloon attack, and melee.
I have not tested this pack with more than one player as Grimm, so if you try, it might break. This is also the first datapack I've uploaded, and the 2nd I've ever made.
