Ring of protection

A ring of protection (sometimes capitalized Ring of Protection) is an enchanted ring that provides magical protection to the wearer. They come in varying levels of enchantment.

Mechanics
Rings of protection require attunement, and provide the wearer with a bonus to their armor class and saving throws. In Exandria, rings of protection can have different levels of enchantment (+1 or +2 to AC and saving throws); in the official rules, however, they only have one level of enchantment (+1).

History
In Tal'Dorei, rings of protection are worn by cyclops stormcallers.

Campaign one: Vox Machina
Rings of protection of two levels of enchantment were available for sale at Gilmore's Glorious Goods in Emon. When Vox Machina came by on a shopping trip, party members Pike Trickfoot and Keyleth expressed interest in one of the rings, and the party purchased it; Keyleth would eventually come into possession of it. Vox Machina would later spend some time divvying up their recently purchased magic items, including the ring of protection, and Vex'ahlia would keep it.

An elderly woman who assisted the Broker in a mission to capture Lillith Daturai wore a ring of protection. After she was killed, Vox Machina looted it off her body. It was likely this particular ring that Vox Machina presented to the fire giant Whaska in the City of Brass as payment for information, which the giant rejected.

Slayer's Take member Kashaw Vesh held a ring of protection.

Campaign Two: The Mighty Nein
Fjord asked shopkeeper Pumat Sol if he had any "articles of protection", such as a ring, cloak, or bracelet. Later, while adventuring beneath Bazzoxan, the Mighty Nein discovered a magical ring that Caleb Widogast magically identified as a ring of protection. The ring was promptly given to party member Yasha Nydoorin.
