Ephemera
by beholderface
With Ephemera installed, Hex Casting gains spells and blocks that build on Hexal's link system, and the mod is an addon for those two mods.
What it does
Ephemera extends Hex Casting with a theme of its own. Its Instant Aegis spell conjures temporary empty armor slots that a caster can fill, and the armor can apply a status effect chosen by the player, which makes the spell adaptable to different fights. Set patterns tied to associated blocks work with Hexal's link system, so more data can be sent across links.
Some content in the Hex Casting addon was migrated from the Oneironaut addon, and the author recommends that players who use it take a look at that content. One spell lets a wisp shoot a plasma beam modeled on the one from Noita. Ephemera requires Architectury API, Fabric API, Hex Casting and Hexal, and it is published for Fabric, Forge and Quilt. Files exist for 1.19.2 and 1.20.1, and the latest build, 0.3.1 for 1.20.1, was released on 2025-12-10 on the beta channel. The server and every player need the mod installed. It is open source under the MIT License.
