Flowstone

Flowstone is a silvery substance made in the reactor core of the Stronghold and used by the Phyrexians to increase the mass of Rath and therefore allow the plane to overlay onto Dominaria. Flowstone was made from magma that was filtered extremely finely until each microscopic molecule was reengineered into a nanorobot that could, through magic, be manipulated into virtually any shape and appear as almost any other material, making it incredibly useful. The black, tar-like impurities created in the process were ejected into the Death Pits. Another function of flowstone was protecting the artificial plane Rath from collapsing by drawing aside its planar boundaries. The ability to control flowstone was one of the main skills of the Rathi Evincars.

Following the Rathi overlay there were large deposits of flowstone left across Dominaria, and a new kind of spellcaster appeared, specialized in controlling flowstone and drawing power from it.

Flowstone is mechanically characterized by +1/-1 or a multiple thereof.
