This angelic creature is in fact the chief of Saradomin forces, who fight in God-Wars Dungeon. Her combat level is 596, which means she is RS gold a mid game boss that is available for all players able to gain access to this area and kill 40 Saradomin creatures which opens door inside her cave. The boss is often the subject of killing to obtain God Sword pieces and Armadyl Crossbow which could be very expensive. Because the battle against Commander Zilyana can be easily repeated she is easy to farm, particularly in close proximity.
Another one from the God-Wars Dungeon bosses is a Cree'arra bird-like creature, which is the leader of Armadyl forces. This boss has a combat level of 580. She specializes in ranged attacks. To enter her room, players must be able to defeat an army of 40 opponents from Armadyl forces and leap through the gap with Mithril Grapple.
Kree'arra is a drop table for death Armadyl items, as also Godsword shards. Because a majority of players play Ranged throughout the game, her drop table is among the most expensive of all God-Wars bosses. Finding Armadyl gear require huge sums of cheap OSRS gold money and due to the fact that fighting isn't very difficult, many players hunt Kree'arra, rather than other bosses.
