Liquid Earth

This spell creates a hemisphere of airy earth, in which normal stone is magically transformed into a thick fog. Within this bubble, creatures not native to the plane of elemental Earth can move through its earth, stone, and clay as if passing through water. The spell also enables those within its area to breathe normally. The spell provides no light, however. The material component is a bent tube of nickel costing 100 gp.

Notes: Common for spellcasters from an Arabian setting; otherwise very rare.
