by a1ex_rom

HexCast NEOFORGED ports the Hex Casting magic system to NeoForge 1.21.1, letting players cast spells by drawing patterns in the world.

NeoForgeClient and serverMIT LicenseOpen source1.21.1

What it does

Spells are built by drawing patterns that the game reads in real time. The programmable system includes more than 150 actions that can be combined into custom effects, and circle casting supports larger, advanced rituals. Staffs, lenses, trinkets and other magical items use the same system, and the mod also adds effects such as brainsweeping and quenched allays.

The port requires Caelus API, Kotlin for Forge, PAUCAL and Patchouli, which must be installed alongside it. Curios API is optional and adds equipment slots for magical items. Compatibility is listed with JEI, Curios, Create and Farmer's Delight. The mod is released under the MIT License and is open source, with its source code and issue tracker public. Files target NeoForge 1.21.1 only, with the latest build 0.11.1-16 published on 2026-07-08.

Key features

  1. Pattern-based spellcasting

    Players draw unique patterns to cast spells, and the game recognizes each drawn shape as it is made.

  2. Programmable magic

    More than 150 actions can be chained together, so players write their own magical effects from them.

  3. Circle casting

    Advanced rituals are cast inside circles, giving a separate method for larger and more involved effects.

  4. Magical items

    Staffs, lenses and trinkets extend the system with more items that channel spells.
