Wings of the Rakers

This white cloak was originally enchanted by a wizard who found a welcome home among the Griff Mountains and the Rakers. While you wear this magic cloak, as a Bonus Action the cloak takes the appearance of white seagull wings and you gain Fly Speed 30 feet. Additionally, when you are flying and you dive at least 20 feet straight toward a target and then hit it with a melee weapon attack, you deal an extra 2d8 damage to the target. The white seagull wings disappear after 1 hour or earlier if you dismiss them as a Bonus Action. Once you use this property, you can't use it again until you finish a Long Rest.
