Mending Nerf is a modification that completely changes the mechanics of the Mending enchantment. Instead of automatically repairing items using experience from XP orbs, this enchantment now functions through anvils but with a unique advantage: the repair material is not consumed during the process (for example, netherite ingots for netherite items). However, the standard anvil mechanics are preserved - the cost of each subsequent repair gradually increases until it reaches the "Too expensive" threshold. This approach makes the Mending enchantment more balanced, requiring players to adopt a strategic approach to repairing valuable equipment.
