This vaguely humanoid creature with a body made of unworked ore emerges from the ground and glances around with coin-like eyes.

Earth Glide (Ex) A burrowing earth elemental can pass through stone, dirt, or almost any other sort of earth except metal as easily as a fish swims through water. If protected against fire damage, it can even glide through lava. Its burrowing leaves behind no tunnel or hole, nor does it create any ripple or other sign of its presence. A move earth spell cast on an area containing a burrowing earth elemental flings the elemental back 30 feet, stunning the creature for 1 round unless it succeeds on a DC 15 Fortitude save.
Metal Mastery (Ex) A metal elemental gains a +3 bonus on attack
rolls if its opponent is wearing metal armor, is wielding a metal
weapon, or is made of metal (such as an iron golem).
Environment any (Plane of Earth)
