Overview

Ex Compressum is a heavy-duty expansion for the Ex Nihilo series of mods, specifically designed to alleviate the repetitive manual labor associated with skyblock-style gameplay. While Ex Nihilo introduces the core mechanics of sifting and hammering, Ex Compressum provides the means to scale these operations through compression and automation.

The mod focuses on three primary pillars: Compression (handling blocks in bulk), Automation (power-driven machinery), and Utility (obtaining animals and resources that are otherwise difficult to find in a void world). It is compatible with modern Minecraft versions like 1.20.1 and 1.21.1, integrating seamlessly with energy systems (FE/RF) and various ore processing mods.
