Apprentice's Codex
by Aquid
Apprentice's Codex is a Forge and NeoForge add-on for Iron's Spells 'n Spellbooks that brings side-grade spells, casting weapons, curios and support blocks into the game.
What it does
Installing the add-on requires Iron's Spells 'n Spellbooks, and it introduces no new creatures, magic traditions, ore veins, biome types or forced advancement steps. Its spell list covers offensive options such as conjured blades and firearm-style attacks, protective measures like walls of force and mana regeneration, plus exploration aids that reveal distant locations, search for structures and sense buried loot. Gathering spells can fell trees, reshape terrain, harvest crops and collect dropped items.
Equipment includes Spellcaster Guns, Swingcast Staves and Offhand Spell Amplifiers, along with several heavier casting weapons and a set of grimoires and runic tablets. Support blocks include the Spellcaster Workbench, Spell Dispenser and a crafting station. Worlds already in progress can pick up the additions without a relaunch, and villages generated afterward may spawn a villager with a new profession.
The mod is published for Forge and NeoForge on 1.20.1 and 1.21.1, with the latest files dated 2026-10-10. Every player and the server need a copy of the mod.
