About
Ozone Skyblock Reborn 2 is an expert-style skyblock questing modpack that guides players from a starting island through hundreds of quests toward crafting creative-only items and completing endgame achievements. It combines technology, magic, exploration, farming, and automation, with major systems from mods such as Mekanism, Applied Energistics 2, Mystical Agriculture, Theurgy, and Industrial Foregoing. Progression includes custom and extended crafting, advanced machines, power generation, and increasingly demanding recipes, with the quest book providing rewards along the way. Beyond the skyblock island, the pack offers space adventures through Ad Astra, an expanded Nether, and exploration of the Aether, Twilight Forest, and other dimensions, alongside structures in the Nether and End. Players can grow mystical crops, build automated production lines, and pursue powerful gear and creative items as they develop their sky base. The pack offers Normal and Expert difficulties, with Expert mode providing the more demanding recipe progression; multiplayer quest rewards can also be shared.

No harmful code found in the projects we checked
We checked 340 of its 344 projects and the files in the pack itself, without running them.
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.

10 mods send something about you
We read the code of 333 of its 334 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.
How we checked
- Go online onlyTheir code contacts a web address, for example to check for updates. We found nothing it sends about you.23 mods

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.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Not on Modrinth.
