KubeJS Iron's Spells
by Wayfarer
KubeJS Iron's Spells lets script authors define custom spells, spell schools, spellbooks and magic items for Iron's Spells 'n Spellbooks.
What it does
The mod adds no content by itself. It is a KubeJS addon that gives scripts access to the Iron's Spells 'n Spellbooks feature set, so spells, their schools and attributes, and the items that carry them can be written in scripts rather than in a separate Java mod.
Scripts can attach spells to staves, spell books and magic swords, hook into event handlers such as PlayerEvents.changeMana, and make mobs cast spells, including changing the AI of existing mobs. Alchemist Cauldron recipes are supported as well. Iron's Spells 'n Spellbooks and KubeJS are both required, and the mod is published for Forge and NeoForge.
The server and every player need the mod installed. Files cover 1.19.2, 1.20.1 and 1.21.1, and the latest files are 6.5-3.14-r2 for 1.20.1 on Forge and 4.0.3 for 1.21.1 on NeoForge. The code is open source under the MIT License.

How it compares
Cataclysm: Spellbooks is a Forge and NeoForge mod for 1.19.2 – 1.21.1 that is open source under the GNU Lesser General Public License v2.1 only. It adds spellbook content for the client and server rather than scripting access. Spells Gone Wrong works on the same loaders and versions but is not open source and carries an All rights reserved license, so it is a content mod rather than a scripting addon.
