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 gains spell resistance 20. The scarab can also absorb energy-draining attacks, death effects, and negative energy effects. Upon absorbing twelve such attacks, the scarab turns to powder and is destroyed.
Strong abjuration and necromancy; CL 18th; Craft Wondrous Item, death ward, spell resistance; Price 38,000 gp.
One of my players is wanting to know if the 12 charges aspect of a Scarab of Protection happens automatically, or if he can decide not to have the protection against energy-draining attacks activate.
In large part this is because he wants to use the rules in MIC to add the properties of an Amulet of Health to the Scarab, but if the protection happens automatically, then that would eventually be a very wasteful use of gold, as after 12 such attacks, the amulet would be destroyed.
I'm leaning toward it happens automatically, and there's nothing you can do to stop it from absorbing the attack while the scarab is worn.
Thoughts?
