A player wearing Ancestral robes.
Ancestral robes can be obtained as rare drops from the Chambers of Xeric. Equipping the robes requires level 75 Magic and 65 Defence.
They are the best-in-slot robes for magic attack, trading off some of the defensive bonuses that Ahrim's robes offer, for better magic accuracy and additional magic damage. They also do not degrade, unlike Ahrim's robes.
The robes can be stored in the armour case of a player-owned house costume room.
The robes can be recoloured using a Twisted ancestral colour kit, which may be obtained from completing a Chambers of Xeric raid in Challenge Mode. It is no different from normal Ancestral robes aside from appearance and becoming untradeable.
