Mod Compatibility:

Pact Magic shines in combination with content mods. In many respects, it works "out of the box" with any other mod. It will do its best to assign spirits to items. You should be able to bind modded mobs, although their AI may react unpredictably to contracts. Biome braziers should function on modded biomes automatically. Modded tools, weapons, and armor should be able to be taken as Implements if they are tagged correctly.

Full integration requires a data pack with custom recipes. Things like item spirits, mob bindings, transfusion recipes, etc. can all be added via JSON files in a special "practice" folder. Custom Familiar perks require a compat mod (Familiars/Implements/Demesnes are exposed as a Forge capability of each player). See the Pact Magic Modding Guide for full information on making datapacks or addons for Pact Magic.

Pact Magic has pre-built compatibility with some mods already, including:

• Alex's Caves (comprehensive compat, these mods go great together)
• Cataclysm (comprehensive compat, fun challenge/reward of binding big bosses)
• Macabre (comprehensive compat and a mini-questline)
• Abyssal Decor (total block/item compat)
• Enemy Expansion (total mob compat)
• Biomes o' Plenty (total biome compat)
• Places (total biome compat, not much else)
• Farmer's Delight and many extensions (comprehensive compat)

Credits:

This mod was developed by Tickbug, inspired by fan-forum interpretations of fictional works by J.C. "wildbow" McCrae. Thank you to TinkerTaylor, Telwyn, Blastnboom, and especially Kvysteran for all the playtesting, debugging, ideating, and encouraging. Thank you to Maws_Enderteeth for post-launch playtesting and contributing data pack recipes.

No generative AI was used in the creation of this mod. Claude code was used briefly for memory leak analysis.

Further Updates:

This is the sprawling side project of a single dev who used it as a way to dip their toes into various aspects of modding, and Pact Magic is unfortunately now way too big to be fully maintained by one dev with an increasingly busy life. There will be intermittent bugfix/balance updates, but there are no plans to port it to other minecraft versions or do huge content drops. Feel free to reach out on the discord if you've made data packs or compat mods that you want to get integrated into the mod.
