by Caelum1920

Focalworks is a Fabric addon that adds rigged foci and spellbook page controls for handling iota data in a spell-casting setup.

FabricServer required, client optionalMIT LicenseOpen source1.20.1 – 1.20.6

What it does

Focalworks adds focus rigging, so a rigged focus can trigger a hex when an iota is read, written or modified as it passes through. A rigged focus can also return a flag on the stack that reports whether the iota went through. Spellbook manipulation lets a caster read the selected page or switch to another. The server needs the mod, and players may add it on their clients. Files are published for Fabric only, across six releases 1.20.1 – 1.20.6, with 1.1.2.3 for 1.20.6 as the latest build. It is open source under the MIT License.
