Where to find Mist Raven in Sekiro

Hirata Estate – Bamboo Thicket Slope Idol
You’ll find the Mist Raven’s Feathers inside a hidden temple. To access it, go up from the idol, grapple left and drop into a body of water. Swim past the bridge and then grapple to a branch. You’ll pick up an item and can look right to slash through bamboo (there’s 3x Spirit Emblem inside). Wall-jump up to the next clearing and you’ll face an enemy that is defending the location.
