Ars Magica 2 Wiki

Liquid Etherium is a sky blue fluid block similar to water which is added by Ars Magica 2. It can be placed and picked up with buckets, but unlike water, is not infinite. Liquid Etherium can be found in the various biomes of the Overworld in pools that are 2x2 or larger that can be up to three blocks deep and more than 5 blocks across, the latter only appearing in magical biomes. Liquid Etherium has many characteristics similar to that of water, such as the ability to turn lava into obsidian and ability to flow seven blocks out when placed. However, it can be placed in the Nether.

Liquid Etherium is notably used to create the Arcane Compendium, by placing a book in an item frame nearby and waiting; however, Liquid Etherium, as of yet, does not have an Arcane Compendium entry.

Usage in the Obelisk

Liquid Etherium is used as a fuel in the creation of neutral Etherium by an Obelisk as a replacement for transforming items into Essence. In order to have the Liquid Etherium fuel the Obelisk, either a Liquid Etherium source or flowing block under the Obelisk as a source of fuel. Keep in mind that the Etherium also cannot be directly below the Obelisk as breaking the block below will also destroy the Obelisk. Once one block is found below it (up to 10 blocks down), the Obelisk will search recursively based off that location in order to find more Liquid Etherium source blocks. Flowing Liquid Etherium blocks are neither consumed or used in the creation of power, but are used to search for additional source blocks. The Etherium source blocks must be directly below the center of the Obelisk to begin.

The liquid Etherium source blocks are eventually consumed, and will provide around 5000 etherium to the obelisk, with potential slight variation.
