This datapack changes numerous things about Minecraft, simply to make the game more annoying for people in general and speedrunners in particular.
Changes include:
- Breaking a log randomly gives you either a log, a plank, or a stick.
- Certain blocks, such as cobblestone, obsidian, and ancient debris, have only a 50% chance to drop when mined.
- Many loot chests have been modified to have less loot.
- Getting a pearl from an enderman, or a rod from a blaze, are now both 50% rarer.
- Crafting tables are crafted with 2 logs and 2 planks.
- Crafting a log into planks only gives you 3 planks instead of 4.
- The lead crafting recipe has been reverted to require slimeballs.
- Several structures are significantly less common (such as villages, shipwrecks, and fortresses).
- The Nether now has a lot more lava.
...and more!
Good luck!
