Flintlock: The Siege of Dawn contains 5 Enki Feather Locations. Finding all Enki Feathers unlocks Ruffled trophy or achievement and increases Enki’s attack and curse damage. There are 3 Enki Feathers in the first map of the game, Three Peaks, and another 2 in the second map of the game, Wanderer’s Rest. While this guide is intended for use during the story, all Enki Feathers can still be found after the story, nothing is missable because there’s still free-roam after the story.

Three Peaks

1. Enki Feather 1: after activating the Lodestone at Gavel Gate, go up the hill on your right and flank the right side to find a skull. Activate it and travel through the opened Rifts to reach an island in the distance. Mantle up to the very top to find this Enki Feather.
   
2. Enki Feather 2: atop a giant wooden structure at the very top of the Enlightened Peak. You can reach this as your progress through Side Quest A Delayed Reunion.
    
3. Enki Feather 3: when you reach the Foglands as part of Main Quest Powder and Steel, this is north of the campsite, atop a tower.
   

Wanderer’s Rest

1. Enki Feather 4: you must collect this to complete the Side Quest Ascension. Ascension can be started in the Cape Reunion territory and the Enki Feather is located on the tallest peak of the territory.
   
2. Enki Feather 5: in the canyon area, at the very top. Must get to it by means of the Rifts that must be activated at the skulls in the area.
   

These are all the Enki Feather locations in Flintlock: The Siege of Dawn.
