About
OPSkies 2 is a semi-expert, technology-focused custom Skyblock modpack built around automation, EMC generation, and a quest-guided progression. Players begin by using Chickens to produce their first materials, then progress along branching technological and magical routes, with each route unlocking mods needed for further advancement. Custom recipes reshape many familiar modded crafts, and key materials lack EMC, so players must automate production rather than rely on ProjectE alone; ProjectE condensers and flowers are disabled, and some EMC-eligible items cannot be learned. The quest book provides a progression path through roughly 1,000 quests, while the pack includes seven dimensions and more than 150 mobs.

No harmful code found in the projects we checked
We checked 420 of its 422 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.

8 mods send something about you
We read the code of 416 of its 419 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.

Mobs Properties RandomnessMade with AI: not checked yet
We have not looked for AI tools in the pack itself 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.
