Found north of Glimmerogg. Rares in Zaralek Cavern do not spawn every day, and don't even begin to spawn until the zone has been loaded for at least half an hour.
Level scaling: Most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
