This datapack removes copper blocks from trial chambers and replaces them with a deepslate pallet, preventing players from getting surplus copper armor and copper tools. This datapack should be compatable with most terrain generation mods/datapacks, unless they directly modify the .nbt files of trial chambers specifically. You can still use datapacks/mods that make trial chambers more or less frequently generating with this datapack.
Replacements
- Copper Block -> Deepslate Bricks
- Oxidized Copper Block -> Deepslate Tiles
- All Cut Copper Block -> Polished Deepslate
- All Chisled Copper -> Chisled Deepslate
- All Copper Grates -> Sometimes replaced with Iron Bars, otherwise Oxidized Copper Grate
