One Piece: Game Master's Guide (Version 2)
This guide presents rules for running adventures in a world of pirates, bounty hunters, and Marines. Characters choose who they serve, determine their allies and enemies, and face the dangers of the Grand Line. The system combines familiar d20 mechanics with setting-specific rules, including survival elements such as managing food supplies and enduring hazardous seas. This second version incorporates most of the material from the Player’s Guide.
技能型（购买或获得技能）基于点数（分配点数以获得技能、能力等）基于属性/数值（STR、CON、PER 等）
