Description

High-Altitude Alchemy is a Skyblock Collection modpack (think ATM: To The Sky) based around using ProjectE transmutation to create and manage your resources.

You've been displaced from your reality by a universe fracturing catastrophe and ended up on a small floating island in a vast void. With nothing to your name except your alchemy tools and a small part of the rift that brought you here in the form of a slice of cake you'll have to put your head to the task of finding a way home!

This modpack does not have traditional skyblock resource mods like Ex Nihilo, you'll have to synthesise all of your materials through a unique progression path utilising the mods available to you with your current resources. Once your pockets are full you can start working on a larger goal: Prismatter, this is a progression-check to see that you've dabbled a little in every mod and can automate a wide variety of items.

Beyond prismatter this pack includes several custom multiblocks, custom singleblock machines and many, many custom items that you will create along your way to even greater heights. This pack features an endgame that involves creative items like many other packs but expects you to use them to accomplish your goal of travelling home!

You'll see many familiar mods such as Mekanism, Botania and AE2, as well as some lesser known new faces like Malum and Embers Aetherworks. Dabble in technology and magic to your heart's desire!

(Please note that this pack is not designed to teach you modded minecraft, work things out yourself, it's a puzzle)
