Altar Emitter

The Altar Emitter is the answer to the first stage of automating the Blood Altar, and was added by Sanguimancy. This block can be set to check the Blood Altar for a given amount of Life Essence, and emits a redstone signal when said amount is reached or passed. The required amount can be modified by right-clicking (+100), or shift right-clicking (-100).

To work correctly, the Altar Emitter needs to be placed in one of the four spots it is in the picture below. A tooltip was added for in-game remembrance.
