I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Adds compatibility between Ars Nouveau and Occultism
Features :
- Spirits can now be used from Containment Jars!
- Spirits automatically pull items around them in a 7x7 area and process them.
- Player can also right-click items on the jar to process them
- Containment Jars containing spirits has an Item Capability attached. In other words, Items can be piped into the Jar! (pipes, hoppers, starbuncles all work!)
- Janitor Spirits have a special functionality where it will automatically try pushing its contents into an inventory on top of the jar
- New recipes to make progression easier
- QoL changes :)
