Desert phoenix is a bird that can be found wandering north-west of the Ruins of Uzer in the northern Kharidian Desert by the clay mines.
During The Golem quest, players must steal one of its feathers and use it with Black mushroom ink to create a phoenix quill pen. Doing so requires level 25 in Thieving; boosts can be used.
