Affinity
by glisco
Affinity is a magic mod built around Aethum, an energy the mod treats as the source of life and its semi-physical manifestations.
What it does
Affinity centers on Aethum Flux, the energy that powers its machinery. Players twist and bend fundamental forces to create magical tools, and the same flux drives technology that the mod presents as magic that has not yet been understood. The mod keeps a balance between traditional magic features and magic-based tech, so both parts of the game feel connected rather than stacked.
Its design draws on earlier magic mods such as Thaumcraft and Botania, aiming for a familiar feel with a different experience. Its guide, Wispen Testament, covers each aspect of the mod in detail and walks players through the steps. Affinity runs on client and server, so both the server and every player need it. It is published for Fabric and Quilt for 1.20 – 1.21.1 and is open source under the MIT License.
Affinity needs Cardinal Components API, Lavender, TerraBlender, Trinkets and oωo (owo-lib) to run. PlayerAbilityLib is bundled inside the mod, so it needs no separate install. Lavender also supplies the guidebook interface that the mod uses.
