Deviate Faerie Dragon

The Deviate Faerie Dragon is a hostile level 19 elite rare mob faerie dragon found on the side heading towards Lord Serpentis in the Wailing Caverns. There is a high chance that it won't spawn at all in the instance. Some estimates place his spawn rate at between 5-10%.

Background
