Iron's Spells 'n Spellbooks:Monsters & Spellbooks
by RedReaper28
Monsters & Spellbooks adds two spell schools, 90 spells, enemies that cast them and gear for Iron's Spells 'n Spellbooks on NeoForge 1.21.1.
What it does
Iron's Spells 'n Spellbooks is required, and the addon adds content to it rather than replacing its systems. New spells sit across the existing spell schools, while a new school focuses on debuffs, damage over time and curses. Hybrid builds can combine two compatible schools, trading some spell strength for more versatility, and an Archmage path keeps a single school's unique skills.
The addon includes 12 armor sets with their own spell statistics, 30 weapons with unique skills, 10 accessories that use a new accessory slot, and 5 ores that upgrade the normal gear of the base mod. Ten mobs cast special spells, and two structures generate in the overworld. Monsters are armed with magic inspired by Minecraft Dungeons, and the fantasy tone draws on games such as Skyrim and Terraria.
Monsters & Spellbooks runs on client and server, so the server and every player need it. Files exist for NeoForge 1.21.1 only, with 0.0.15 as the latest build from 2026-07-12. The code is open source under the MIT License. Source code and an issue tracker are linked publicly. Development is ongoing, so content may be reworked, removed or added in later updates.
