Ocular Gems

These fist-sized gems gleam with the shimmering magical energy that boils within them. A beholder can fit one of these items into an eyestalk's place by pulling the stalk slightly back into its body to create a shallow socket in its hide. Wearing an ocular gem grants a beholder the use of a new supernatural ability from the list below that operates just like its other eye rays. In theory, a beholder could use as many as ten ocular gems by retracting all its eyestalks, but few beholders are willing to give up all their racial eye rays. Unless otherwise specified, the ability granted by the gem has a range of 150 feet. Other races cannot use ocular gems.
