Windskiff
Wondrous item, rare

- Cost: 4,000 gp
If you want to travel between the Moonshaes, you won’t be able to on foot, by horse, or by cart. You’ll need to sail. And while you could simply hire a boat, where’s the fun in that?
This small piece of jewelry has 3 charges and regains all expended charges daily at dawn. While you are holding it, you can take a Magic action to expend 1 charge, which causes the jewelry to transform into a sail-powered personal vehicle. The vehicle is roughly the size and shape of a household door with a 10-foot-tall sail extending from one side. After 1 hour or until you use the item’s command word (no action required), the transformation ends and the Windskiff reverts to its jewelry form.
In vehicle form, a Windskiff is a Medium object with the following statistics: AC 12, HP 30, and Speed 40 ft. The Windskiff hovers a few inches above whatever surface it’s on and can glide; it moves 5 feet horizontally for every 1 foot it descends in the air. A Windskiff and its riders take no damage from falling.
