Altar dragon

Altar Dragons are the religous dragons of Runescape. They are the only dragons that follow gods. While they have no levels, they can be fought and their HP depends on the amount of monsters you have fought and successfully defeated. For example, if you have fought and successfully defeated 300 monsters throughout your entire playing on Runescape, they will have somewhere between 600-800 HP. They also lack an examine text up to this point. Dragons that follow Saradomin are blue, while Guthix dragons are green and Zamorak Dragons are red. Armadyl dragons are white while Bandos dragons are orange.

Trivia

 * Once defeated, they do not die. Instead, they take light to follow the afterlife of the god they choose. Because of this, they lack an item drop, but still have an XP gain.
 * There is no Zaros dragon yet. Jagex said they are working on a black Altar Dragon, but it is unknown if this will be a Zaros dragon.
