Iron's Spells 'n Spellbooks: Unstable Magic
by AstraLight
Unstable Magic is a NeoForge addon for Iron's Spells 'n Spellbooks that adds a chaotic explosive school and a set of destructive spells.
What it does
The addon introduces a new spell school built around explosives and hyper-velocity attacks, aimed at players who want far more firepower than the base spell set offers. Its spells include an orbital nuke that calls down a ring of explosive energy from the sky, a stabshot that drives a descending pillar of force into the ground, and an orbital bomb that condenses a large amount of explosives into one point for an instant detonation. Unstable Railgun fires a piercing arrow across long distances and can blink the caster, and Spyglass Landmine plants a harmless-looking spyglass that explodes on anyone who steps too close.
Other spells summon spectral knights that stay invisible and silent, and a pack of wolves that swarms enemies from the sky. The school also has an Unstable Core, a condensed volatile heart that drives the new magic. Unstable Magic requires Iron's Spells 'n Spellbooks, the base mod it extends, and it is not open source: the code is under All rights reserved.
The mod is installed on client and server, so the server and every player need it. Files are published only for NeoForge 1.21.1, with 0.6.0 as the latest file, dated 2026-07-02. The mod was first published on the same date.
