About
Sigma is an expert skyblock modpack built around a ten-stage progression in which players create resources and automate increasingly advanced production, though the progression can be bypassed. Early stages use Create’s rotational power to produce resources such as iron, gold, and clay, then Blue Power’s Igniter and Block Breaker to reach the Nether and gather materials. Alchemistry introduces atomization and replication to produce chemicals and Useless Ingots, leading to RF-powered machines and Silent Mechanism’s complex alloys, plastics, and expanded automation. Later stages feature turtles, quarries, and quantum storage; GM crops grown for resources; and fission and fusion that supply materials for Overloaded Physics. The final stages move into Overloaded equipment, including an Infinite Capacitor and powerful armor, and then challenge players to bend the laws of physics with Creative Energy Cells.

Security
No harmful code found in its mods
We checked all 106 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 projects106 mods
- Files in the pack itself446 settings files, 14 scripts, 33 other files, no mod jars.
Privacy
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.8 mods
- Send nothingTheir code contacts no web address.97 mods
AI
AI used in 6 of the 66 mods we checked
We found an AI tool in them, or their authors declared AI content.
40 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.
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.
