Atomized

You wake up on a tiny island in the void with a chemistry set, a dream, and way too many elements to memorize.

This is a 1.20.1 Forge skyblock pack where the entire game leans into one core idea:
take the world apart with chemistry, then rebuild it into something unreasonably overengineered.

What this pack is

A chemistry-driven skyblock.
Your progression is built around Alchemistry and Chemlib. You’re not just smelting ores; You’re dissolving blocks into elements, recombining them, and abusing the periodic table to get anything you want.

ProjectE with an actual identity and careful configuration.
Only elements have EMC. No free netherite button, no “turn cobble into creative power in 5 minutes.” You'll build an elemental economy: True Equivalent Exchange.

Industrial Alchemy
Custom multiblocks let you scale your labs into full-blown industrial nightmares: higher throughput, faster reactions, bigger numbers. You don’t just add “more machines,” you build proper chemical production lines.

Tech that wraps around chemistry.
Power, item logistics, and automation are chosen to make your chemistry setups feel like real infrastructure, not a sidestep to be overlooked. Mods like ProjectExpansion allow easy linkage of automation systems to your EMC network.

Worlds Beyond

Incendium Nether.
The Nether is a vertical, lava-lit hellscape full of weird geography and nasty surprises. It’s actually worth gearing for; not just a pit stop for quartz. be warned, it is not to be taken lightly.

Ad Astra: leaving the void entirely.
Once your chemistry, power, and infrastructure are online, you can go off-planet. Build rockets, touch down on other planets, set up low-gravity mining outposts, and pipe rare resources back into your reactors and labs while braving strange worlds.

Nullscape End.
The End gets a glow-up into a strange, haunting endgame dimension. Floating islands, eerie vistas, late-game resource routes. Beyond this point, there be monsters.

Scorched Guns 2: mobs scale with your hubris.
The longer you play, the stronger the mobs and their guns will get with night time raids to keep you on your toes. You’re building reactors, black hole apparatus', and sky-factories; the world is absolutely allowed to be upset about it. GLHF.

Late Game: “OSHA Left The Server”

NuclearCraft: Neoteric.
Design your own reactors, visit The Wasteland(yes, you read that right, a whole new dimension), and eventually drag power and more out of black holes. Radiation keeps score. If your base looks cursed, your lifespan will too.

Brains over brawn: Psi & ComputerCraft.
For players who like to think sideways:

• Psi gives you programmable spell-tech, perfect for weird utility and movement tricks.
• ComputerCraft lets you script turtles, network your base, and overcomplicate literally everything in the best way.

There are more mods quietly supporting all of this; QoL, extra toys, little bits of chaos. However, the heart of the pack is chemistry + EMC + automation + exploration, all feeding into each other.

Quests, pacing, and vibes

• The questbook walks you through the early skyblock grind and the core chemistry loop, then gets out of your way.
• The pack is tuned for long-term worlds, servers and big bases.
• Servers are incredibly easy to make using our partner Wabbanode and the included Server Pack for each version(starting at v1.3.1+ the server pack can be found under 'Additional Files' for a given version's release in the 'Files' tab)
