Thurbrand's protector

Thurbrand's protector was the battered wooden kite shield of the famous Cormyrian warrior Thurbrand of Arabel.

Powers
The +1 protector functioned as a similarly enchanted ring of protection and was impervious to permanent damage, as it magically sealed any cracks or breaks throughout the frame overnight.

Additionally, when the wielder rapped on the frame three times with their fingers or knuckles, the shield produced a bubble of air, 10 feet in radius. This globe moved with the shieldbearer, granting them breathable air within any gases or liquids through which they traveled.

History
Originally found within the hoard of a dragon, the protector was wielded for years by Thurbrand. After some time, he sold it to King Osbrun of Tsurlagol within the Vast. Some time around 1351 DR, the shield was looted in a grand theft of the city-state's royal armory. Its whereabouts after that were unknown.
