Tool Levels

A pickaxe gains experience from two categories of blocks, stone and ore, and each category has its own level track. Stone leveling adds mining speed bonuses, while ore leveling adds mining speed and an extra drop chance. The two tracks progress independently, so a pickaxe can be strong at stone and still low at ore.

Each level requires a set number of blocks, and the requirement and the bonus amounts follow a configurable curve. Progress is stored in the pickaxe's NBT data, so a pickaxe that is lost or replaced loses its progress too. The action bar shows the current level and the blocks left until the next one, while toast notifications, a level-up sound and a fireworks effect mark each advance. A maximum level is set by default and can be changed in the configuration.

Tool Levels is a Forge mod for 1.20.1 and runs on client and server, so both the server and every player need it. The mod is released under All rights reserved and is not open source. Its configuration covers the block requirement per level, the speed and drop chance bonuses, the toggles for the action bar, toasts, chat messages and sounds, and a custom ore block list with a stone blacklist for modpacks that add extra ore blocks.
