This left-handed black iron gauntlet appears little more than a dull soot-stained plated glove at first glance, but in truth it is a powerful boon granted by a god to his most faithful subjects.
Placing the glove on your left hand causes excruciating pain as your appendage curls into a tight fist and then slowly transforms to supernaturally hard black stone. You cannot use your left hand for anything beyond smashing it into objects or creatures (you cannot carry a shield or secondary weapon and you take a –4 on skill checks that usually require two hands).
The gauntlet cannot be removed without a successful casting of remove curse, break enchantment, or a similar spell. The gauntlet grants you a +2 enhancement bonus to Strength and acts as a +1 adamantine gauntlet. The item also grants you the ability to use the gauntlet as a secondary natural attack. In addition, the Grasp of Granite allows its wearer to use stone shape once per day.
