Occultism

Occultism is a magic mod created by klikli_dev. A spirit-summoning magic mod where players bind demons and djinn to perform tasks like mining, crafting, and transporting items. As a magic mod it concentrates on spells, rituals, and arcane progression, and it has been downloaded around 18 million times, which puts it among the options players reach for in this space.

Occultism is built for players who want a summoning-and-rituals magic mod with helpful spirits. It centres on summoning spirits to automate tasks, store items in a pocket dimension, and perform rituals, with a distinctive occult theme. It rewards a bit of learning, so expect to spend some time understanding its systems before they click.

The mod is available for Forge and NeoForge, so it fits a range of modpacks and launchers. It currently supports Minecraft 1.20.1 and 1.21.1, spanning the 1.20.1 to 1.21.1 releases. It runs on both the client and the server, so on a multiplayer server every player who connects needs it installed alongside the server itself.

Occultism works particularly well alongside GeckoLib. It depends on GeckoLib, so those must be present and on the same loader and version. It targets the Forge side of the ecosystem, so it fits comfortably into Forge and NeoForge packs.

Occultism has a modest footprint for what it adds and is widely used in modpacks without notable performance concerns.

If you are comparing options, similar mods include Ars Nouveau and Blood Magic. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
