As with all capes of accomplishment, when a player operates this cape, they will receive a small boost (to 100 instead of 99). This is useful for repairing Barrows armour, as well as repairing Torva armour, Pernix armour and Virtus armour in a player owned house, as it lowers the cost of said repairs. Talking to Thurgo gives an option to toggle the appearance of the cape to a retro version, overriding the normal appearance and making it look similar to how it did before the 2015 graphical update. Despite it not being a new item, the retro cape can be used with a dragon keepsake key.
