This project has moved to Planet Minecraft.
This data pack removes the mending enchantment from loot tables, as well as swapping out any Mending enchantment on items and books the player acquires with Unbreaking 3.
I recommend you use this data pack alongside my Anvil Mending data pack so you can always repair your enchanted items, without any increased cost in experience, using an anvil and the relevant repair material item.
This data pack is also compatible with my Chest Loot Upgrade (version 9+), and Chosen Enchantments (version 4+) data packs.
