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.

Earth Strike (Ex)

When an earth elemental warrior is reduced to 0 hit points, it explodes in a burst of elemental energy, dealing 2d6 damage to all creatures within 20 feet. A creature that makes a successful DC 14 Reflex save takes only half damage. This save DC is Constitution-based.
