This artifact is a silver ring with claws clutching a blue pearl. Cantrik glyphs inscribed around the inside of the band give an incantation for the protection spell. The ringbearer enjoys a +1 to AC and saves, and a magic-user can use the ring as a talisman to cast protection. The ring's normal effect, the talisman spell, and the magic-user's own spell can all stack together, if desired.
The ring was round in the tomb of the Agha-yin prince Mayna-yood-sashai, in the catacombs beneath the temple of Zhothaqquah.
