Burrow (Ex): A xorn can glide through stone, dirt, or almost any other sort of earth except metal as easily as a fish swims through water. Its burrowing leaves behind no tunnel or hole, nor does it create any ripple or other signs of its presence. A move earth spell cast on an area containing a burrowing xorn flings the xorn back 30 feet, stunning the creature for 1 round unless it succeeds at a Fortitude save.

Xorn qualities

Immunities (Ex): Xorns are immune to fire and cold.

Resistances (Ex): Xorns have electricity resistance 10.

Half Damage from Slashing (Ex): Slashing weapons deal only half damage to xorns, with a minimum of 1 point of damage.

All-Around Vision (Ex): Xorns' symmetrically placed eyes allow them to look in any direction, bestowing a +4 racial bonus to Spot and Search checks. Xorns can't be flanked.

Tremorsense (Ex): Xorns can automatically sense the location of anything within 60 feet that is in contact with the ground.
