A necklace with a small marble stone in the shape of a circle that coils around itself. The stone channels magic from the wearer's body and the surrounding environment to create a faintly shimmering dome around the wearer that wards against any harm.

Upon attunement the wearer gains a magical shield worth 10 temporary hit points. If the shield has taken any damage it will regneratate 1 temporary hit point back for every hour the wearer takes no damage.
Additionally as long as the shield has at least 1 temporary hit point left it offers the wearer +1 AC.

Notes: Bonus: Temporary Hit Points, Bonus: Armor Class, spellcaster.
