Earthenair

This spell causes the earth surrounding the target creature to surge upward and inward in a violent eruption of dirt and rock. The number of rocks created by the spell is 1d4 plus the level of the caster. Each rock causes 1 point of damage to the target, disrupting spellcasting and counting as one successful attack for purposes of the stoneskin spell. The rocks are considered to be magical missile weapons for purposes of determining whether a target can be successfully attacked by them.

This spell does not work if the target is standing on a solid stone surface (such as bedrock, not flagstone) unless the caster is 10th level or higher. The earth remains somewhat scarred where earthenair is cast unless it is physically tidied up after the spell is finished.

The material component for the spell is the priest's holy symbol and a handful of pebbles that are hurled toward the target.
