Volo's rejuvenating ring

Volo's rejuvenating ring was an enchanted ring created by Elminster Aumar for his friend Volothamp Geddarm some years before the late 14 century DR.

Powers
This small unassuming ring granted the wearer increased vitality and, once per day, the wearer could cast cure critical wounds spell.

History
At one point after being presented to Volo, the writer found himself swept away into a plot that crossed the merchant princess Sa'Sani with whom he was enamored, and the interloper deity from another world – Zehir. When the god's avatar was slain by a group of adventurers who worked for Sa'Sani, Volo gifted them this magic ring as a gesture of a personal gratitude.
