Summon Earth Grue

The spell opens a gate to the Elemental Plane of Earth, summoning an earth grue, also known as a chaggrin or soil beast, to the caster. The caster need not fear that the summoned grue will turn on him or her. Neither concentration on the activities of the grue nor protection from it is necessary. The summoned earth grue helps the caster in whatever manner possible: attacking the caster's foes, tunneling in the general direction desired, and so on. It remains for a maximum of three rounds per level of the caster. It returns to its home plane if slain or sent back by a dispel magic spell or similar magic.

The material components are the priest's holy symbol and an unworked raw metals worth at least 50 gp. The latter is offered as a bribe to the creature during the casting, and must be handed over to the creature before it will enter the Prime Material Plane.
