by BielGG

BielGG's Spells Addon extends Iron's Spells 'n Spellbooks with new magic schools, spells and boss content for Forge.

ForgeClient and serverMIT License1.20.1 – 1.20.6

What it does

The addon adds several magic schools to Iron's Spells 'n Spellbooks, including Shadow, Unstable, Relicron, Infinity and Tainted, along with new spells, upgrade orbs and rune spellbooks. Its spell and school content is layered on top of Iron's Spells, and players can use it with the rest of their spell setup.

The addon also works to bring older Cataclysm models, references and renderers in line with newer versions, and it integrates with Cataclysm: Spellbooks and Manuscripts magic schools where those mods are present. Each spell multiplier, school multiplier and specific spell value can be adjusted in the config file, which lets server owners decide what the addon allows.

It is published for 1.20.1 – 1.20.6 and requires Crash Assistant, Curios API, Iron's Spells 'n Spellbooks and L_Ender's Cataclysm. Client and server: both the server and every player need it. The code is released under the MIT License, and the project is not open source.

Key features

  1. Additional magic schools

    Shadow, Unstable, Relicron, Infinity and Tainted schools add spells and items to the Iron's Spells 'n Spellbooks system.

  2. Rune spellbooks and upgrade orbs

    Upgrade orbs and rune spellbooks improve a range of spell types, adding progression to the existing school system.

  3. Config-driven spell multipliers

    Spell multipliers, school multipliers and values for individual spells can be changed in the config file.

  4. Boss encounters

    A Broken Script boss has a phased moveset including tornado captures, corrupted player clones and Unstable Blink bombs.
