Kubejs Pufferfish Skills
The author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
PufferfishSkillsJS is an addon mod for Pufferfish's Skills that adds KubeJS integration. It allows modpack creators to control skill tree behavior more easily through KubeJS, such as configuring repeatable skills, listening to skill unlock events, giving custom rewards, and modifying skill experience or skill states.

Main Features
- KubeJS API Support: Manage Pufferfish's Skills categories, skills, experience, rewards, and unlock states through scripts, making it easier for modpack creators to write custom logic.
- Skill Event Listeners: Provides events for skill unlocks, skill locks, category unlocks, category locks, and repeatable skill upgrades. These events can be used to run commands, give items, modify attributes, or integrate with other systems.
- Repeatable Skills: Allows selected skills to be upgraded repeatedly after being unlocked, consuming skill points each time and triggering the corresponding rewards again.
- Datapack and Script Integration: Designed to work with datapack-based skill trees and KubeJS scripts, making it suitable for classes, talents, roguelike progression, attribute upgrades, and other custom gameplay systems.
