Knaprium Eternal
by KacK30
Knaprium Eternal is a NeoForge expansion for 1.21.1 that adds the Knaprium material, machines and a set of mobs, equipment and food to a world.
What it does
The mod centers on Knaprium, a material obtained through three machines for infusion, extraction and refining. Its gear and armor are balanced around the mod's own progression system, so a player working through the chain meets the new items at a steady pace. The author describes the content as a solo experience, with magic, automation and exploration as recurring themes, and notes that the current version leans most on magic.
Curios API is required, and the new items will not work without it. Knaprium Eternal runs on client and server, so the server and every player need it. Files are published for NeoForge only, for 1.21.1 alone, with version 0.1 dated 2026-07-19 as the latest file. The mod is released under the MIT License and is not open source.
Key features
Knaprium material
Knaprium is the core material of the mod, produced and processed through a chain of machines.
Three processing machines
Infusion, extraction and refining machines turn raw inputs into Knaprium and its derived parts.
Balanced armor and gear
Armor and other equipment are tuned against the mod's progression, with the author noting they can feel strong next to other mods.
Mobs, food and magic
Extra mobs, food and magic content widen the mod beyond its machines, and the author treats magic as its main emphasis.

Use cases
Solo progression
Players who want a self-contained progression route can follow the Knaprium chain without relying on another expansion's power curve.
Modpack design
Pack developers can use the mod as written or adjust its balance, which the author encourages for modpacks.
Who it’s for: Players who enjoy magic, automation and exploration in a solo world, and pack developers who want a Knaprium-based progression with NeoForge.
How it compares
SC Eternal runs on NeoForge for 1.21.4, uses the Apache License 2.0 and is not open source. Dimensions & Dungeons targets NeoForge 1.21.1 and is also a client and server mod under the MIT License. Knaprium Eternal is built for 1.21.1 only, so it does not overlap with SC Eternal's version.
