Ars Nouveau

Ars Nouveau is a magic mod created by baileyholl. A spell-crafting magic mod where players compose custom spells from modular glyphs, with familiars and enchanting systems. As a magic mod it concentrates on spells, rituals, and arcane progression, and it has been downloaded around 35 million times, which puts it among the options players reach for in this space.

Ars Nouveau is built for players who want to design their own spells from reusable components. Spells are crafted as glyph sequences on a Spell Book, mixing forms and effects so two players rarely end up with the same toolkit. 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.

Ars Nouveau works particularly well alongside GeckoLib, Patchouli, and Curios API. It depends on GeckoLib and Patchouli, 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.

Ars Nouveau 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 Iron's Spells 'n Spellbooks and Botania. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
