Ring of the Fallen Phoenix

Once belonging to Captain Torshal, ex member of the Lofthaven Phoenix Knights, the ring was recovered from his body by The Eyes of the Archon during the reclaiming of Retherdale. 
The Ring can be activated as an action, lasting for one hour. While active, an invisible shield appears around the wearer, increasing their armor class by 2, and increasing the armor class of one ally of their choice within 5 feet of them by 1.
The ring is recharged on a short rest
It is currently attuned by Savic Lofthaven
