Essentia Tubes are both a research option that can be purchased with experience after researching Essentia Distillation, and a block. Essentia Tubes, in this basic research, come in the standard Essentia Tube, and the Essentia Valve. This research also unlocks the creation of the Essentia Resonator. Using Essentia Pipes, one can automate the movement of Essentia from one place or another, but this usually requires a rather complex system where many problems could easily arise. The Essentia Resonator can be used to help find issues such as these to fix them, such as competing amounts of suction from different sources. All things capable of taking in Essentia have a suction value. The greater this suction, the further away it can draw Essentia from. However, suction values can compete for Essentia, which will leave pipes hissing and spitting steam with the Essentia moving nowhere. The basic Essentia Tube moves Essentia with no special properties or benefits, while Essentia Valves can be turned on and off to allow or disallow Essentia from moving through them. The standard Essentia Tube can be created in batches of 8 by placing a single piece of glass in the center of an Arcane Workbench, along with 2 iron ingots in the middle left and right sections, a Quicksilver Drop in the top middle section, and a gold nugget in the bottom middle section, along with 5 Ordo and Aqua Vis. The Essentia Valve can be created with an Essentia Tube and lever placed in an Arcane Workbench, along with 5 Ordo and Aqua Vis. Finally, the Essentia Resonator can be created with a stick in the bottom middle section of an Arcane Workbench with a piece of Nether Quartz in the center, and 4 iron ingots in the left and right middle and top sections.
