A Suit of armour was an animated piece of armour that could be found in Taverley Dungeon. When players tried to open the gate by the skeletons that leads to the cauldron of thunder, the two suits of armour on the sides would come to life and attack them. They were mainly encountered during the Druidic Ritualquest, and they could either be killed or ignored.
This monster can still be viewed in the RuneScapeBestiary. In High Detail, its shield resembled a Zamorak kiteshield with a light grey colour added to it. Before the graphical update, it appeared to wield an iron longsword.
