Alderium
by Ysuzen
Alderium is a Forge equipment mod for 1.20.1 whose main material is used to craft tools, armor and a backpack that are slightly better than their netherite counterparts.
What it does
Alderium serves as the base material for a set of tools, armor pieces and a backpack. Each of these items is crafted from the metal and gives slightly stronger stats than the netherite version. The mod also adds Endersteel, which uses Alderium in its recipes and is a little better again, and Neantite, which uses Endersteel together with a multitool. Blue Topaz is a separate ore that follows the same pattern, and its iron-tier helmet grants water breathing.
The mod is licensed under the Apache License 2.0 and is not open source. It runs on the client and the server, so both sides need it, although the author states that multiplayer support is not finished and that the mod is intended for single-player worlds. The mod is not recommended alongside other mods and is incompatible with some of them. The author notes that the project is paused and will not receive updates, and that the English text has known issues that will be corrected later. Recipe viewers such as REI and JEI list its crafts.
