About this Mod

⚠️ Low Beta Version

The goal of this project is to create a large One Piece-inspired RPG experience in Minecraft with combat systems, Devil Fruits, factions, exploration, ships, world events, and a complete pirate progression system.

Planned features include:

  • Canon-inspired attacks and abilities
  • Fighting styles and Haki
  • Devil Fruits with strengths and weaknesses
  • Crews, factions, Marines, and reputation systems
  • Islands, kingdoms, and world structures 
  • Ships and exploration systems
  • Story progression and endgame content
