Install oωo (owo-lib), Trinkets, Lavender, Cardinal Components API and 2 more first. We found matching files for this game-version and loader setup. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Affinity add?

Affinity is a magic mod all about Aethum, an energy emanating from and necessary for all manifestations of life, and its semi-physical counterpart Aethum Flux. Discover how, through twisting and bending these very fundamental forces, you can create powerful magical tools, useful machinery powered by Aethum Flux and take control over life and death.
All the while, it maintains a tasteful blend between the traditional features of a magic and a tech mod - after all, magic is only tech that we have not yet understood. Inspired by the likes of Thaumcraft and Botania, Affinity strives to deliver a somewhat familiar yet brand-new experience, building on what those mods did well and improving where there was potential left on the table.

The Wispen Testament

The Wispen Testament, Affinity's comprehensive guide, covers every aspect of the mod in detail and leads you along every step of the way. Built using Lavender, it delivers an intuitive, familiar and seamlessly integrated guidebook experience.

Credits
Affinity has been a huge undertaking over 3 years in development and would not have been possible without the help of many people. I, glisco, extend my thanks to:
- naschhorn and pvpTurtle, for spending countless hours with me brainstorming ideas, balancing and testing the mod
- Pois1x, for providing many of the textures in the mod
- chyzman, for inspiring countless little and some more major features
- BasiqueEvangelist, for his occasional code contributions and ideas
- Aikoyori, for their texture and model contributions
- Noaaan, for helping with gameplay design and his inexhaustible knowledge on the game's armor and weapon systems
- Halbzwilling, for inspiring me to start modding all those years ago and strongly influencing some parts of Affinity's design through his NoGravity datapacks
- The remaining Wisp Forest team for their moral support and just overall being a great bunch of people
To anybody else who has inspired me, or someone else on the team, thank you!
