Progression Plus
Progression Plus inserts a Mystium tier between iron and diamond, with its own tools, armor and enchanted book crafting for NeoForge players.
What it does
Mystium is a new ore tier that sits between iron and diamond. It cannot be crafted into tools on its own; it has to be combined with iron tools at a smithing table. Items made from it are stronger than iron and weaker than diamond, which keeps early mid-game gear from jumping straight to diamond.
Enchanted books can be crafted from a book surrounded by specific items, so a blaze powder arrangement produces a Fire Aspect book. Mystium armor trims and more advancements extend the progression, and the author notes further content, including a possible boss, without fixing its details. The mod runs on NeoForge for 1.21.4 – 1.21.8 and is published under the Creative Commons Attribution Share Alike 4.0 license, so it is not open source. Client and server both need it.
