Hex Casting

Curseforge | Modrinth | Source

Banner, showing the name of the mod, a staff, some bookshelves, and some amethyst.

A mod for Forge and Fabric adding stack-based programmable spellcasting, inspired by Psi.

  • Cast Hexes on-the-fly without having to pre-compile them by drawing patterns on a hexagonal grid
  • Craft items that can cast Hexes and give them to your friends
  • Uncover ancient lore
  • Descend into madness
  • Do unspeakable things to the sentient life clinging to the barren world

> this feels like the whole "almost die from overcasting for enlightenment" thing but in real life
-- Matt6049

Getting Started

Read your journal! You should spawn with it. That's your guide to the mod. Everything you need to know should be unlocked in there over time.

Requirements

This mod requires PAUCAL. On Forge, it also requires Patchouli and Kotlin for Forge, and on Fabric it also requires Patchouli Fabric, Fabric Language Kotlin, Cardinal Components, and Cloth Config.

And yes, you can put it in your modpack, or stream/make videos of it! (Without needing to ask! Although if you're making a series featuring Hexcasting I would like to know 🙂)

Will this mod be updated?

Yes! We're currently working on a port to 1.21.1, along with a variety of new features. Alpha builds can be found here if you want to try things out as soon as they're implemented. If you run into any bugs, please help us out by opening an issue to report them.

There is no 0.11.0 or 0.11.1 due to bad planning.

Changelog:

  • Update to Minecraft 1.20.1!
  • Patterns render in-world around you to other players! Freak people out with your casting prowess, or disrupt your opponents by reading their spells. Thanks, Amo!
  • Move flight to pre-Enlightenment; choose between infinite flight in a small radius, or a short-lived flight with infinite range.
  • Altiora -- a Great Spell that gives you fragile elytra wings.
  • Quenched Allays -- generate media out of allays. Comes with a decorative staff and blocks, and ONLY ONE TEXTURE APIECE.
  • Shepherd Directrix -- pop a boolean from the stack and choose which branch of a spell circle to take.
  • Thought-Knots -- cheap foci you can only write to once.
  • Lots of new decorative blocks thanks to the indefatigable Falkory.
  • Actually let you read the lore I implemented last update and forgot to include anywhere. RIP Cardamom Steles.
  • Performance and evaluator improvements mean that there is no longer a recursion limit, and you can execute many more patterns at once before the server yells at you.
  • Patterns now render in text as patterns instead of the old HexPattern(...) format. Thank Sam for this wizardry.
  • A lot of mathematical patterns work better with multiple types; you can add numbers and vectors, for example. This means there can be fewer patterns overall because they each work with more types.
  • Overcasting works better, especially if your max health is different.
  • 196 bugs closed and 143 merge requests accepted since the last release!
  • Explosion now damages entities when used at eye level.
  • You can't cheese the Flay Mind mishap to insta-kill your victim anymore.
  • Fixed a lot of cheesy ways to cast spells without needing media.
  • Fixed the bug where we had no devops
  • Removed Hexxybrine
