AscensionCoreAPI is a developer-focused addon framework for KumoDesu Ascension. It allows other mods to add custom races, evolutions, classes, skills, stats, models, textures, animations, hitboxes, magic behavior, and progression systems without directly modifying KumoDesu. The API also handles integration features such as data synchronization, persistence, race-family compatibility, event hooks, and helpful version diagnostics. It adds little gameplay content by itself—it is intended as a foundation for KumoDesu addon mods.
