Fist of stone

Fist of stone was a simple transmutation spell common among practitioners of the province of sand in Zakhara.

Effects
The spell allowed the caster to transform one of his or her fists into living stone. The stone hand could still move enough to pick up and manipulate items but not with enough dexterity to complete spells with somatic components. Having a hand of stone was useful for crushing or breaking items or for making more powerful punching  or grappling attacks. It was also particularly useful for smashing the hull of wooden sailing vessels or spelljammers.

The hand did not increase in size or change shape; it simply turned into stone. This effect lasted for at least one minute but sometimes longer for more powerful wizards.

Components
The spell required at least verbal and somatic components. The somatic components were complicated and ended with punching the air with the fist to be transmuted. Some variations of fist of stone also required a small stone inscribed with a fist icon for use as a material component.
