Magma Elementals

Magma Elementals are the brutes of the Elementals, being usually nothing but dumb, and burning, muscle, they have no thought capabilities, and very little vocal skills to boot, meaning that they're always ignored or killed. The main reason that they're so dangerous is because they're made of magma,  and constantly let off superheated steam, and the occasional burst of magma, which generally allows them to only exist inside volcanoes. They can control a magma, and the more skilled ones have a small amount of control over fire as well. Think of them as an upgraded Fire Elemental, combined with an upgraded Earth Elemental.
