Copper-Free Trial Chambers
Changes Trial Chambers to not utilise an absurd amount of copper blocks. Also backports changes to Trial Chambers from 1.21.2.
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.

May contain Grated Copper
Changes the design of Trial Chambers to not utilise an absurd amount of copper blocks.
Also backports the 1.21.2 trial chamber changes to 1.21!
