The Animated Steel Armour has the attacking speed of a scimitar, despite wielding a longsword. It also uses it as a stabbing weapon, whereas players can only use it for slashing.
Steel armour, along with several other armours, received a graphical update on 31 January2012. However, animated armours were not graphically updated until 24 June2013.
After an update on 18 August2014, Animated Steel Armour in the Warriors' Guild had its weakness changed to crush attacks. It was previously weak to water spells, though players could not exploit the weakness due to only melee being usable against it.
