Earthenport

When this spell is cast, priests becomes attuned to the rock surrounding them, allowing them to use rocks of at least the same volume as themselves and the nonliving material they carry as teleport gateways. This gives the priest (alone) the ability to teleport without error to any location on the Prime Material Plane that has a large outcropping of rock. Priests take 1 turn to travel from their original location to their new location. During the first five rounds they are fading into the rock from their starting point and during the last five rounds they are emerging from the rock at their destination. After the end of the last round of the spell's duration, they may act normally; until then they are visible, but immune and intangible to all magical, physical, and psionic attacks except transmute rock to mud, dig, stoneshape or similar spells.

Use of this spell is not without its dangers, however. Should the priest be the target of a transmute rock to mud, dig, stoneshape or similar spell during the spell's duration, the priest suffers 4d6 points of damage (no saving throw allowed) and must make a successful saving throw vs. spell or be stunned for 1d4 rounds.
