Scarab of protection

Scarab of Protection: This device appears to be a silver medallion in the shape of a beetle. If it is held for 1 round, an inscription appears on its surface letting the holder know that it is a protective device.
The scarab’s possessor can choose to have the scarab absorb up to 35 HP of necromancy damage. The scarab can also absorb energy-draining attacks, death effects, and negative energy effects.  Each absorbed effect takes a charge, when it expends the last charge, the scarab turns to powder and is destroyed.
