By means of this spell, the wizard can form an existing piece of stone into a shape that suits his purposes. For example, the wizard can make a stone weapon, a special trapdoor, an idol, etc. This spell can also enable the spellcaster to reshape a stone door so as to escape imprisonment, providing the volume of stone involved is within the limits of the area of effect. While the caster can thus create stone doors and coffers, the fineness of detail is not great. If the construction involves small moving parts, there is a 30% chance they do not function.
The material component of this spell is soft clay that must be worked into roughly the desired shape of the stone object and then touched to the stone when the spell is uttered.
