Endium Expansion
by huntersheik
Endium Expansion, a NeoForge world generation mod for 1.21.5, adds an Endium ore deep in the End and a gear tier that sits above Netherite.
What it does
Endium Ore is a rare block found only in the outer parts of the End dimension, deep within the island terrain. Mining it requires a Netherite pickaxe, so the material is gated behind the existing top tier of vanilla progression. Endium ore smelts in a furnace or blast furnace into Endium Scrap, which is the base ingredient for the next steps.
Endium Scrap is combined in a crafting table with five Eyes of Ender to produce one Endium Ingot. Endium gear is then built at a smithing table from Netherite armor or tool pieces together with Endium Upgrade Templates. Those templates are a rare drop: Shulkers have a chance to drop them on death. The mod is aimed at players who want a tier beyond Netherite and are willing to travel to the End for it.
The mod is published for NeoForge only, with one file, version 1.0.0, built for 1.21.5 and released on 2025-05-01. The server and every player need the mod installed. Endium Expansion requires no other mod, and it is licensed under All rights reserved, so it is not open source.

How it compares
Strider657's End Update is a NeoForge mod for 1.21.1 – 1.21.8 that is also client and server, under All rights reserved, so it is not open source. Endorium Mod is a NeoForge mod for 1.21.8 only, also client and server and not open source. NetherStuff is a NeoForge mod for 1.21.4 with a client and server environment, released under the MIT License and open source, so its source code is public. Endium Expansion covers only 1.21.5, so it does not match any of these version ranges.
