Decent low price for the amiibo, always a bit skeptical how they get received, but this felt like one worthy of a share. NBP based on ShopTo.
The Zelda & Loftwing amiibo releasing alongside The Legend of Zelda: Skyward Sword HD can be used at any time while exploring the overworld or dungeons to create a checkpoint and return to the sky. Tapping the amiibo again while in the sky or visiting one of the many floating islands above the clouds returns you to the checkpoint you previously created.
Hope it helps someone.
