Elden Ring: Where to find Stormhawk Feather and what it does

Stormhawk Feather is most typically found in and near Elden Ring's Stormveil Castle. The Warhawk, huge eagles found at Stormveil Castle and Crumbling Farum Azula, is the most common enemy that drops Stormhawk Feather. The Stormveil Castle guards will also infrequently drop Stormhawk Feather. Just after the Stormveil Cliffside Site of Grace, we got one from a guard with a trumpet.

A Stormhawk Feather can also be found on the ground near the Liftside Chamber Site of Grace in the castle courtyard; on a corpse near the road north of Stornveil Castle; and on a corpse far to the east of Stormveil Castle near the collapsed bridge. Gatekeeper Gostoc will sell you up to five Stormhawk Feathers for 500 Runes apiece. When you initially arrive at Stormveil Main Gate, he will encourage you not to utilize the main gate, and when you've received the Rusty Key, he will become a trader.

Stormhawk Feather is only used in one preparation, which is for Stormwing Bone Arrow, a powerful knockback ammo type. You'll also need Thin Animal Bones and the Nomadic Warrior's Cookbook [10] to make Stormwing Bone Arrows.
