Milestone capes are a series of nine cosmetic Capes of Distinction that are 'earned" each time all of a member's skill levels reach a multiple of 10. They were released on 3 May 2011, and first mentioned in the developers' blog "Capes of Distinction". Players who have leveled every skill above level 10, 20, 30, and so on, will be able to weave a special cape on a loom. Unlike other Capes of Distinction, this cape does not come with the accompanying hood, nor an emote. Each milestone cape comes with a defense bonus that increases with the level required for the cape. All nine of the milestone capes can be stored on the player-owned house cape rack.
To make a milestone cape, you need to weave one yourself at a loom. Making a cape requires one ball of wool per 10 levels. For example, Milestone cape (10) requires 1 ball of wool, while Milestone cape (40) requires 4 balls of wool. A total of 45 balls of wool is required to make all nine milestone capes per skill.
The milestone capes appear to stick out more from the neck compared to other capes.
