The Magmatic Engine is an engine that runs on lava. If the amount of energy it outputs is more then the amount used by the network it will power down until it locks up and requires being hit with a Crescent Hammer to restart.

Recipe
The Magmatic Engine is crafted with three Invar Ingots, one Redstone Transmission Coil, two Invar Gears, and one Piston.
