Glass Cannon
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.
Glass Cannon
This custom challenge gives you an insane damage output, making you capable of killing everything in just one hit. On the other hand, you own health is limited to half a heart, which means that the same applies to you as well. The intended goal for this data pack is to defeat the ender dragon, though of course you may use it for whatever you have in mind.
This data pack was originally made for version 1.16, but it still works up to 1.20.2 (and probably later versions if you're reading this in the future).
