Explore a pirate world of islands, ships, and One Piece powers.
Modpacks get no grade of their own, so we show the grades of its mods. Of its 168 graded mods, 123 are graded A or B, 37 C and 8 D to F. Its last update came out 8 months ago, for Minecraft 1.20.1. See the mods
One Prime Piece builds on True Prime Piece to create a focused adventure inspired by the One Piece anime, centering play on pirate life rather than unrelated RPG and adventure content. Character choices include multiple races and classes, Haki, Devil Fruits with abilities for fighting, movement, and exploration, and distinct fighting styles. The world is almost entirely ocean, with scattered islands that make exploration and seafaring central to the adventure. Players can design, build, and sail functional pirate ships between islands, and equip armor ranging from One Piece-inspired designs to original pirate-themed sets. New structures inspired by notable locations reward exploration, while handcrafted quests guide progression with challenges and rewards.
Written from CurseForge . How we write it
The mods of its newest release (Minecraft 1.20.1 · Forge, 28 Feb 2026). Each check result is for the latest files of that mod, which may not be the version in this pack.
Compared with the release of 4 Feb 2026 for the same platform, Minecraft version and loader. We do not compare the versions of the projects yet.
Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.
5 mods send something about you
We read the code of all 162 of its mods, without running it.
Why we show this: a modpack runs the code of its mods, and a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
AI used in 2 of the 136 mods we checked
We found an AI tool in them, or their authors declared AI content.
5 other mods show AI use only from after this release (28 Feb 2026), so it does not apply to the versions in this pack.
26 mods are not checked yet.
No sign so far that AI was used to make the pack itself
We looked for AI tools in its texts and found none.
We have not read its files and images yet.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
