What it does

The mod centers on seven souls drawn from the series' core traits, including Kindness and Patience. Two further souls, Fear and Hate, are also included. Players can hold right click with a soul in the main hand to obtain a unique item or weapon tied to it.

Underforge also adds nine unique weapons, among them a Dagger, Tough Glove, Scythe, Empty Guns with Bullets, Pan, High Heel, Toy Knife, Notebook and Hatred Knife. Recipes for these items are included, and the gallery shows several recipe variants that produce the same item.

Underforge is published only for Forge and only for 1.20.1. Every player and the server need a copy of the mod. The mod is not open source and is released under All rights reserved.
