The resourceful Gnomish Inventors have designed an amazing craft known as the Submarine. This watertight vessel can submerge beneath the waves and surreptitiously keep watch on enemy forces above the surface. The Gnomish Submarine is visible only to Towers, aerial forces, and other vessels that move beneath the waves. Using cunning and craft to carry out surprise attacks on more powerful enemies makes the Submarine an invaluable part of the Lordaeron armada.
