Mending Tools Dependent On Type

The Mending Enchantment Is An Enchantment That Is A Must. It Requires Increasing Levels In An Anvil To Repair Your Tools. Mending Just Costs 1 xp for 1 Durability

I believe that the more durability your tool has, the more it takes to achieve getting 1 durability point.

Netherite would require a lot of xp to be repaired while gold and wooden tools would be a 1 to 1 xp to durability ratio.
