Monks of Zamorak worship the god of chaos, Zamorak. The monks have formed groups and worship together at altars scattered throughout RuneScape. They attack with melee and magic attacks. Unlike Saradomin monks, they do not heal players and do not have a "Talk-to" option. The only place that monks of Zamorak talk is in the Wilderness. Some monks are aggressive and attack when players approach them. They are able to use stat draining magic attacks. In the Myreque questline, they ally with Saradominist monks in order to find a way to break the Edicts of Guthix, but ultimately fails.
In one Treasure Trails clue, a Zamorak Monk must be slain to obtain a key that opens drawers in the Edgeville Monastery. Monks of Zamorak at the Chaos Temple and the entrance to the Ourania altar will drop this key. Monks of Zamorak at Paterdomus do not.
During the Defender of Varrock quest, when the zombies attack the Varrock Palace, the imprisoned Monk of Zamorak can be shouting various phrases: "Kill those guards!" "Let me out! I'm a bad guy too!" "Someone want to get me out of here?" "So are any of you zombies gonna break me out?" "Hey! Zombies, I'm on your side." "Haha, mash those guards" "Let me out, I'll help with the invasion!" or "Oi, Mr. Zombie, Can you let me out?"
