What this mod does
Arcanum is a programmable magic mod: instead of picking spells from a list, you build them by linking nodes in a visual editor on a hexagonal grid. There are logic, flow, targeting, cast shape and effect nodes, and the author’s motto sums up the idea: magic as engineering.
How you progress
- First you craft the Arcanum Forge at the regular workbench, with rock, gold ingots, crystal and bone fragments.
- Spells run on a CAD, the magical «hardware»: from the Copper CAD (3 slots) to the Adamantite CAD (12), with more complexity allowed at each tier.
- Codices, dropped by enemies and found in chests, unlock nodes; the more you have, the higher your max mana (from 100 to 500).
- Spells can be shared as codes.
Update 7
Version 0.6.3 (October 12, 2026) is the build for 0.7 and declares compatibility only with the 0.7 branch. It bundles Patchly 3.6.2, respects block-breaking permissions and changes the controls: with a CAD equipped, Ability 2 (E) now selects a fragment and crouching cycles backward. Update 7 introduces its own runes and mana bar; the page doesn’t explain how they coexist with the mod’s system. It’s still in active development and the balance may change.

Highlights and things to keep in mind
- A very original magic system: you design the spells yourself
- Clear progression with seven CAD tiers
- Documentation on GitHub and an update the same day as Update 7
- In active development: balance and spell behavior may change
- Steep learning curve compared to magic mods with a fixed spell list
- The GitHub documentation asks for Zima and MultipleHUD even though CurseForge doesn't list them
- All Rights Reserved license
Requirements
- Hytale (Early Access) on PC or server, version 0.7 (file Arcanum-0.6.3.jar)
- Patchly is included in the file (embedded library)
- The author's GitHub documentation also asks for Zima and MultipleHUD; CurseForge doesn't list them as dependencies
How to install it
- Open the Zen's Arcanum page on CurseForge and click Install to set it up with the CurseForge app, or download Arcanum-0.6.3.jar from the Files tab (the file marked 0.7).
- If you download it manually, copy the file as is, without unzipping it, into the mods folder: on Windows, %APPDATA%\Hytale\UserData\Mods.
- Open Hytale, right-click the world, check Zen's Arcanum in the mod list and save the world settings.
- On a dedicated server, put the file in the server's mods folder and restart it.
- Craft the Arcanum Forge at the workbench and then your first CAD; check the author's getting-started guide on GitHub.

Common problems
Do I need to know how to code?
Not strictly: spells are built by linking pieces in a visual editor. But the more complex the spell, the more it feels like designing a small program.
How do I get more nodes?
With the Codices dropped by enemies and found in chests. Each one unlocks a node of its type (logic, effect or trigger).
Does it work on 0.6?
No. For 0.6 you have to stay on 0.6.2; 0.6.3 declares compatibility only with 0.7.
