Ex Compressum is an Ex Nihilo addon that provides tools to reduce the initial grind in skyblocks in a balanced way.

In Minecraft 1.10.2, it supports both Ex Nihilo Omnia as well as Ex Nihilo Adscensio.

In Minecraft 1.12, it supports Ex Nihilo: Creatio.

In Minecraft 1.20.1, it supports Ex Nihilo: Sequentia, Ex Deorum and Fabricae Ex Nihilo.

In Minecraft 1.21, I'm not aware of an Ex Nihilo port yet.

Features

• Compressed Hammers to break Compressed Blocks into nine of their smashed version (e.g. Compressed Gravel -> 9 Sand)
• Compressed Crook which is four times as fast as a normal crook, but only twice as durable
• Heavy Sieve to sift compressed blocks directly, at a small loss of efficiency
• Auto Compressor to automatically compress items into blocks (e.g. Broken Ores into Ore Gravel)
• Auto Sieves and Auto Hammers
• Wooden Crucible to extract water from plants, as an alternative to rain
• Animal baits that can be placed to spawn cows, pigs, chicken, sheep, ocelots and wolves outside of their natural biome
