About
High-Altitude Alchemy is a ProjectE-centered skyblock modpack about escaping a reality-fracturing catastrophe and finding a way home from a small island suspended in the void. Rather than relying on traditional skyblock resource-generation mods such as Ex Nihilo, its progression asks you to synthesize materials from your starting resources and use EMC transmutation to build up what you need. A central progression check is Prismatter, which calls for exploring the pack’s different mods and automating a broad range of items; later stages include Cosmatter and Luminessence, leading toward the goal of travelling home. The pack combines technology and magic from mods including Mekanism, Botania, Applied Energistics 2, Malum, and Embers Aetherworks. Along the way, you create custom items, single-block machines, and multiblocks, with questlines including Refraction, Building an Arsenal, and Coalescence. Its endgame uses creative items in service of the journey home, and the pack is designed as a puzzle to work through rather than a guide to learning modded Minecraft.

No harmful code found in its mods
We checked all 163 mods 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.
How we checked
- Its projects163 mods
- Files in the pack itself620 settings files, 46 scripts, 617 other files, no mod jars.

4 mods send something about you
We read the code of all 163 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.
How we checked
- Go online onlyTheir code contacts a web address, for example to check for updates. We found nothing it sends about you.15 mods
- Crash reports or usage dataTheir author declares crash reports or usage data on Modrinth, or such a service is named in their files. Reading their code did not show it.1 mod
- Send nothingTheir code contacts no web address.144 mods
AI
AI used in 5 of the 134 mods we checked
We found an AI tool in them, or their authors declared AI content.
4 other mods show AI use only from after this release (7 Sep 2026), so it does not apply to the versions in this pack.
29 mods are not checked yet.
Made 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.
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found in the descriptionChangelogs not read yet
