How to Host a Mine Piece World Server (Forge 1.20.1)
Mine Piece World turns Minecraft into a One Piece battle arena — pick a character, unlock Devil Fruit abilities and Haki, and clash in structured PvP arenas built around the series' iconic locations. It's a Forge 1.20.1 pack with over 22,000 downloads, and unlike free-roaming anime-combat packs such as Attack On Titan Final Stand or the open-world Epic Jujutsu, Mine Piece World is built specifically around arena-select battles rather than exploration — so hosting it right means setting up for PvP from the start, not a survival world.
Start with at least 5 GB of RAM allocated to the server. That's the recommended floor for Mine Piece World's Forge 1.20.1 setup — the character abilities, Devil Fruit effects, and Haki systems all run extra entity and particle logic that adds up fast once more than a couple of players are fighting at once.
Import the modpack directly from its official source instead of guessing at the mod list from a client export — CoalHost's modpack installer pulls the exact Forge 1.20.1 version and dependency set Mine Piece World needs, so you're not left hunting for missing Devil Fruit or Haki mod jars afterward.
Watch the console through the first boot and don't invite anyone until it finishes loading cleanly — confirm the character-select menu, Devil Fruit abilities, and arena world generation all come up without errors before treating the server as ready.
Only open the server to players after that first clean startup. Mine Piece World's PvP arenas and character selection depend on several interlocking systems, and a server that crashes mid-setup can leave players stuck without a character or abilities.
Take a backup before importing a new arena world, updating the Forge loader, or changing combat and ability configs — a bad update can wipe character progress, Devil Fruit unlocks, and arena state that players have no way to get back otherwise.
Use a cleaner Mine Piece World path
CoalHost is built around modpack hosting, which makes Mine Piece World much less annoying to launch correctly.
