Mage Robe of Cold Resistance

Mage Robes of Cold Resistance protect the wearer only against magic of a cold nature, including from weapons and projectiles.

In-game description
"Mage Robes of Cold Resistance are a common sight in the Sword Coast region, especially as one travels north towards Neverwinter and the Icewind Dales. Many young mages receive it as a gift from their instructors upon successfully completing their first five years of study. As with other such robes, they can only be worn by those of the wizardly profession."
