Iotic Spellbooks
by Mephodio
Iotic Spellbooks connects Hex Casting with Iron's Spells 'n Spellbooks on Forge, so casters can read and cast Iron's spells from inside a Hex Casting grid.
What it does
Hex Casting and Iron's Spells 'n Spellbooks are both required, and the mod needs both of them to run. Once installed, it adds an interop layer between the two: a Hex Grid opens for casting, and a Counterspell cast from vanilla Iron's Spells closes the grid and clears it. Iotic Spellbooks also supports spells from addons, so spells beyond the base set can take part.
The mod adds new Hex Casting patterns for working with Iron's spells. Patterns can read spell scrolls and their iotas, cast a spell on the caster or on another entity, and conjure a spellbook. A helper entity can cast an Iron's spell at a chosen position and direction. Files are published for Forge 1.20.1 only, with version 1.1.0 as the latest file, dated 2026-03-14.
The mod runs on the client and on the server, so both the server and every player need it. It is open source under the GNU General Public License v3.0 only, and public links exist for the source code, the issue tracker and the wiki.
