Something's Rotten in Faerun
Scarab of Protection (6 charges)
If it is held for one round, an inscription will appear on its surface letting the holder know it is a protective device.
The possessor gains a +1 bonus to all saving throws vs. spell. If no save is normally possible, he gets a one in 20 chance of saving, adjusted by any other magical protections that normally give bonuses to saving throws. Thus, this device allows a saving throw vs. spell at base 20 against magic missile attacks, for example. If the target also has a +4 bonus for magical armor and a +1 bonus for a ring of protection, any roll of 15 or better would indicate that the missiles did no damage.
The scarab can also absorb up to [charges] level-draining attacks (two level drains count as two charges), death touches, death rays, or fingers of death. However, upon absorbing [charges] such attacks the scarab turns to powder—totally destroyed.
