This mod lets you earn Proficiency for valid upgradeable items by doing things such as:

Dealing damage
Killing mobs
Receiving damage
Picking up XP orbs
Breaking Blocks

You can upgrade items in an anvil with the required proficiency and levels, as well as the necessary material(s).

Upgrades can be reset by combining with Crying Obsidian (configurable).

You can Limit Break items by combining two of the same item that have maxed base upgrades, so two times with 5 slots both need 5 upgrades, and the resulting item is the left item with 5+1 slots. This can only be performed once. (configurable)

There are no included upgrades, as this is designed solely for modpack devs.

For pack devs:

There is also a new Potion Effect, "Mastery", which increases the new "Mastery' attribute (gearupgrades:mastery) by 0.25 per level. This multiplies all basic proficiency-gaining methods, excluding usage in Anvils.

Commands also exist that affect the item held in the main hand:

/gearupgrades <Player> <add/set/remove> <amount>

You can also make any item grant proficiency by adding a "Mastery" (double) tag to an item's Tag, which works similarly to repairing items in anvils.

Included is an example datapack and resourcepack to give you some basic ideas on how to set things up.

Here is information on how datapacks work for this mod:
