Basilisk Gem

This clear gem contains a micro sized basilisk inside. The user may spend a bonus action to cast the spell Darkness centered on the gem. It contains 3 uses which do not recharge. As an action, the user may smash the gem on a hard surface, destroying it. When smashed, the gem emits radiant light in all directions in a 60' radius. Creatures within the radius must make a constitution saving throw (DC 16) or take 4d8 radiant damage and be blinded for 1 round. On a successful save, a creature takes half as much damage and is not blinded. Any creature who averts their eyes (as a reaction) has advantage on the saving throw.

Notes: Damage: Radiant, Blinded
