Java mod listed for Minecraft 1.19–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Adds a way to one-shot all of the bosses that exist in Vanilla Minecraft. If it wasn't obvious enough, these are not early game items and should only be obtained in the late game to become more powerful and to generally make the harvesting of nether stars easier to make beacons faster.
