Mod Pufferfish's Skills

Pufferfish’s Skills, a configurable skill framework

Pufferfish’s Skills is a Minecraft Java mod that provides a framework for building fully configurable skill systems rather than a complete skill tree on its own. Creators can define categories, connected skills, costs, requirements, rewards, experience and progression through JSON data, while a dedicated editor simplifies skill layout design.

Its API and commands allow deeper customization and server administration. Compatible with Fabric, Forge and NeoForge on both client and server, it is ideal for RPG modpacks and progression focused Minecraft server experiences. At BoxToPlay, we recommend it for creating meaningful player choices and long term character development.
