Specterium
Specterium is a Forge mod for Minecraft 1.20.1 that adds a soul-infused metal, a progression of Sculk-themed foods, weapons and decorative blocks, built around a ritual altar and pact scrolls.
What it does
Specterium is built on Soul Remnants, which are refined into intermediate Spirit Alloys and then forged into Specterium Ingots, the mod's top material. Specterium is presented as a metal stronger than Netherite, and it gives access to a set of post-Netherite weapons, tools and armor. Crafting the final ingot requires the earlier materials, so the path from Soul Remnants to Specterium forms the core progression of the mod.
Alongside the metals, the mod adds new foods, a Sculk-themed food line, and decorative blocks such as Sculk Bricks and Soul Bricks. Ectoplasm is a liquid that applies the Ectoplagerised effect, which gives Slowness and Darkness for a set duration.
The mod is published only for Forge, and every file targets 1.20.1. Specterium is released under All rights reserved and is not open source. Two quality-of-life recipes are included, and the author recommends JEI for browsing them.
