Any tool in a player's inventory will slowly repair itself over time, provided it is enchanted with mending.
This does not replace or remove the regular XP repair function of the mending enchantment.
Tools repair themselves so slowly that unbreaking still feels powerful, XP farms still feel worthwhile, and having multiple tools to extend grinding sessions is still optimal.
On default settings, tools will repair themselves on the scale of hours - roughly 1 durability per minute.
Requires Fabric API, Mod Menu, and Cloth Config
