Necklace of Fireballs

Necklace of Fireballs: (16,8d6)(8,16d6)(8,24d6)(4,32d6) If the necklace is being worn or carried by a character who fails her saving throw against a magical fire attack, the item must make a saving throw as well (with a save bonus of +7). If the necklace fails to save, all its remaining spheres detonate simultaneously, often with regrettable consequences for the wearer.
