Frozen key piece (armadyl)

The Frozen key piece (armadyl) is dropped by Aviansie, Spiritual mages, Spiritual warriors and Spiritual rangers within Armadyl's Eyrie inside the God Wars Dungeon. If combined with a frozen key piece (zamorak), frozen key piece (saradomin), and frozen key piece (bandos), it will become a frozen key, which can be used to open the door to the Ancient Prison.
