Temple guardian

The Temple guardian (also known as Cerberus, thus sharing the same name as the hellhound boss, Cerberus) is a dog-like monster that dwells in the entrance of the underground passageway to Canifis.

Players are required to kill the Temple guardian in the Priest in Peril quest. Magic or a cannon cannot be used to kill it.

It is considered a dog in regards to Slayer assignments.
