Armor (hide), artifact
When a single person touches Xanith's Armor of Cold, it feels merely cool. But when a second person touches it while the first still is, it feels freezing. The wearer has resistance to fire damage.
This crude armor consists of thick furs and pelts.
Notes: Resistance: Fire
Don't remember Xanith? *sigh*
