Transmute Sand to Stone (Reversible)

This spell turns a volume of sand into an equal volume of sandstone. The caster can shape the sandstone into any simple form as desired (no great definition is possible), provided no single portion is smaller than one cubic foot and none of the shape exceeds the range.

The created sandstone occupies the same space as the sand it replaces occupied at the time of casting. Creatures standing with their feet buried in the sand at the time of casting are allowed a saving throw vs. paralyzation to jump free (if possible), those trapped will have to break free. The fact that an area of sand has been turned to sandstone cannot readily be seen after the spell is cast (the DM may require an Intelligence check to notice this, for example). The magically created sandstone breaks down into sand particles over a period of 2d6 days.

The material component for the spell is sand ground between two pebbles.

The reverse of this spell, transmute stone to sand, allows the caster to change any type of un-worked stone to sand (sandstone, granite, gems, etc.). Solid rock turned to sand may cause those standing on it to lose their balance and fall (Dexterity check to avoid). This spell has no effect on constructions made of stone or stone like material, or upon composite materials such as clay bricks or concrete. Golems of stone or gem material suffer a -2 penalty to their attack rolls and Armor Class.

The material component for the reverse is sand from an hourglass.
