Item Level Up

Overview

With this mod, most tools, weapons, and armor are levelled up as they're used.  As an item goes up in level, it gains 1 or more bonuses to stats.

In order for an item to gain experience, it must be used for it's associated task correctly.

Tools gain experience by harvesting blocks (not to be confused with destroying them), 1 point per block.
 
Weapons gain experience by attacking and damaging mobs, 1 point per hit.

Armor gains experience by taking and blocking damage, 1 point per pre-reduction damage taken.  Note: damage from sources that bypass armor suck as magic, /kill, starvation, or anything else in the damage tag will NOT give experience!

This mod is focused on configurability so almost any item can be made to have custom level up effects.  Currently only vanilla items are supported out of the box. 

While this mod is required on server and client, all of the configuration is handled through datapacks.

This mod looks for the data/domain/levelup folder to load providers from, and has a few basic defaults as examples.
