About this project

What does ISS: Additional Spells add?

More Magic. More Possibilities.

ISS: Additional Spells is an expansion for Iron's Spells 'n Spellbooks focused on expanding what each school of magic can actually do.

Rather than simply adding more ways to deal damage, Additional Spells introduces new utility, traversal, support, control, and combat options designed to feel like natural extensions of the existing spell schools.

Swap places with an enemy using Ender magic. Electrify a body of water with Lightning. Sacrifice your own health to empower Blood magic. Create paths with Ice, manipulate enemies with Eldritch magic, support allies with Holy spells, and much more.

Built to Feel Like Part of ISS

The goal is simple: fill gaps in the existing schools without replacing the spells that already make Iron's Spells 'n Spellbooks great.

New spells are designed around the identity of their school and use Iron's Spells 'n Spellbooks and vanilla Minecraft assets wherever possible, helping them fit naturally alongside the base mod.

This is only the beginning. Future updates will continue expanding each school with new kinds of magic, with a particular focus on giving every school meaningful options both inside and outside of combat.
