High-Altitude Alchemy is a challenging Skyblock Collection modpack built around ProjectE transmutation instead of classic Ex Nihilo. Stranded on a tiny island in the void with only alchemy tools and a mysterious slice of cake, you’ll synthesize every resource through a unique progression path.
Master technology and magic with mods like Mekanism, Botania, AE2, plus Malum and Embers Aetherworks. Progress toward prismatter as a global automation check, then push into custom multiblocks, singleblock machines and many custom items. Endgame creative items aren’t the finish line – they’re the tools you’ll need to finally find your way home.
