Ancithium Mod
by JasonPegasus
Ancithium Mod adds a second netherite-style material, Ancithium, that players refine from Netherite Scrap and craft into heavier armor and tools.
What it does
Ancithium is presented as the pure form of the metal that netherite is alloyed from, so the mod gives players a way to work with that material directly. Holding Netherite Scrap in the main hand and right-clicking a lava cauldron produces Ancithium Remnants, though half of those attempts destroy the scrap instead. Ancithium Remnants are the next step, and nine of them craft into a single Ancithium Ingot that is used like a regular ingot in other recipes.
Armor is the main focus of the mod. A full Ancithium set gives the same protection as a full set of Diamond Armor, and it also grants Fire Resistance, Resistance III, and Heaviness. Heaviness is a mod-specific effect that limits horizontal movement and jump length, so the armor cannot be used to bypass the slowness effect. The mod is client and server, so both the server and every player need it. It is released under the Creative Commons Attribution 4.0 license and is not open source. Files are published for NeoForge only, for 1.21.1, with 0.5.0 as the latest file.
Key features
Ancithium refining
Netherite Scrap is converted in a lava cauldron, with a chance of losing the scrap on each attempt.

A new effect that clamps horizontal movement and shortens jumps, applied to players wearing the armor.

Use cases
PvP, bosses and dungeons
The author notes that the armor is not meant for constant play and is intended for specific situations such as PvP, boss fights and dungeons.
Who it’s for: Players who want heavy, high-protection armor for specific fights, and server owners who want a defined trade-off between protection and speed.
How it compares

Legacy Netherite is also a NeoForge mod for 1.21.1 with client and server, but it is released under All rights reserved and is not open source. Real Nether runs on Fabric, Forge, NeoForge and Quilt for 1.20 – 26.2 and only needs the server, with optional client installation.

What the author says
This small mod adds a new way to understand Netherite, and squeeze the full potential of the ancient material to its peak. The Ancithium is the "pure form" of Netherite. By itself, Netherite is an alloy composed of impure Ancithium (Ancient Debris) and Gold. By this we can assume that piglins on their times weren't…
