Concept art of the armour.
The Black Knight captain's armour, also known as Captain Dulcin's armour, is a cosmetic armour set obtained and used during The Death of Chivalry quest. It is found in the garden of Edgeville Monastery after starting the quest, and is used to impersonate Captain Dulcin. This armour will make the wearer appear male if they are female.
Items[]
After the quest it serves no useful purpose, apart from using it to enter the Black Knights' Fortress and can be reobtained from the same location. It is made up of five items, none of which have any bonuses:
- Black Knight captain's helm
- Black Knight captain's cuirass
- Black Knight captain's gown
- Black Knight captain's gauntlets
- Black Knight captain's boots
A full set of this armour can be stored in the armour case of a player-owned house.
