Forbidden Tinkers

The mod adds materials and modifiers that strengthen tools and weapons. Champium is presented as an endgame material with stronger stats and traits than the other materials. Modifiers such as Sharpness and Haste take only an upgrade or ability slot, so a tool can hold one of each per slot, and the Upgrade and Ability slots can be expanded with hoppers, cactus or ender pearls as set in the datapack.

Champium is crafted in Champium Forges found deep underground in the overworld. Those forges accept large stacks of farmable materials such as wheat and potatoes and output Champium, so players do not need to gather it in bulk. Tinker's Diamond is a rare underground material that drops only one per mined block and cannot be obtained normally. A Forbidden Tome applied to a tool adds the Overloaded modifier, which doubles the level of the associated modifier, so Sharpness V becomes Sharpness X.

The mod requires Mythic Tinkers and runs on client and server, so the server and every player need it. Files are published for Forge for 1.20.1 – 1.20.6, and the latest file is 1.0.9 for 1.20.1. It is released under the MIT License and is open source. The author recommends it for large modpacks and notes that it breaks the vanilla Tinkers balance, so a custom datapack is advised.
