Description

Project Isothermal can be ran on computers with at least 4 gigs of allocation. Not too taxing.

There are no passive or aggressive mob spawns or any way to duplicate them. Instead you must create them through Compact Crafting.

This modpack revolves around Compact Crafting to get you through each gate.

End game for the pack is creative items created through both Compact Crafting and Extreme Crafting.

 

World Type: Skyblock | Mob Difficulty: NULL | Recipe Difficulty: Expert | Mod Type: Tech/Magic | Theme: Gated

Those who wish to report bugs can do so at projectisothermal.bugs

You can watch me develop and test this pack and others over at kikiisyourfriend.tv/projectisothermal
