The earth walk spell enables the priest to pass into and through stone and earth as if he or she was a xorn (movement rate of 6). This ability allows ambushes in which foes have a -3 penalty to their surprise rolls.
The spellcaster can carry up to twice his or her body weight (total) through the stone as well. For the spellcaster to use this ability offensively, the priest must make a successful attack roll to grab the subject, who is then allowed a saving throw vs. petrifaction to break free. If the saving throw fails, the spellcaster imprisons the subject (as the 9th level wizard spell imprisonment). A freedom spell (the reversed form of imprisonment) can free the trapped creature.
A phase door cast on the earth-walking priest instantly slays him or her.
Notes: Granted by the dwarven god Dumathoin.
