Orb of Incineration
This glass orb is filled with a dark red light. An Orb of Incineration is very fragile, and breaks and detonates when it is thrown and hits the ground. If the holder is hit by an energy attack, the Orb must make a saving throw at a +8 bonus or detonate.
When the orb detonates, everything within a 20 ft radius of it is dealt 10d6 fire damage, 10d6 electricity damage and 10d6 cold damage (reflex save DC 19 for half.)
