EMC for Iron's Spellbooks

Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.

by KURONAMl · on CurseForge

ProjectE EMC for Iron's Spells 'n Spellbooks: adds EMC to its arcane essence, mithril, pyrium and other materials so you can transmute them.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

EMC for Iron's Spellbooks

Play Iron's Spells 'n Spellbooks with ProjectE and its materials have no EMC value. This data-only add-on fixes that.

Hand-tuned EMC for the core materials — Arcane Essence, raw Mithril, Pyrium, Cinder Essence, Hogskin, Dragonskin, Divine Pearl, and the rest.
Most crafted content (ingots, runes, the smithing-upgrade gear chains) derives its EMC automatically from the mod's vanilla-style recipes once the base materials are valued.
Pyrium is priced high on purpose — it converts into ancient debris, so a low value would be an EMC duplication exploit. Mining stays the real path.
Stateful items carry no EMC by design: spellbooks, scrolls, weapons, staves, armor, and upgrade orbs all hold stored spells, durability, or upgrade data that ProjectE shouldn't price.

It adds no items, blocks, or recipes — only EMC data. Values apply on world load; open a Transmutation Table to see them.

Dependencies

ProjectE — required
Iron's Spells 'n Spellbooks — required
NeoForge 1.21.1

The fluid-based ink and elixir items (made in the Alchemist Cauldron) aren't valued in this first version. EMC values are a considered first pass; balance feedback is welcome on the issue tracker.
