Ars Ocultas
by mystchonky
Ars Ocultas links Ars Nouveau and Occultism, so spirits can work inside Containment Jars filled through pipes, hoppers and starbuncles.
What it does
Spirits from Occultism can now be placed in Containment Jars. Once inside, a spirit pulls nearby items within a 7x7 area and processes them, and a player can also right-click an item on the jar to process it by hand. Containment Jars that hold a spirit expose an item capability, so pipes, hoppers and starbuncles can feed them directly. Janitor Spirits push their contents into an inventory placed on top of the jar, and the mod adds recipes that make early progression smoother.
Ars Ocultas requires Ars Nouveau and Occultism. Both must be present on the server and on every player's client, because the mod runs on client and server. Files are published for Forge and NeoForge, with builds for 1.19.2, 1.20.1, 1.21 and 1.21.1. The latest NeoForge file is 1.21.1-2.6.1 for 1.21.1, and the latest Forge file is 1.20.1-1.2.2 for 1.20.1. The code is open source under the GNU Lesser General Public License v3.0 only, and the source and issue tracker are public.
