Costumes

Including the starting costume, there are a total of six collectible costumes that can be found throughout the game. As of now, they have no special effects aside from the sixth costume.

Collecting all outfits will earn the Full Wardrobe achievement.

Default Costume
This is the default outfit that you have equipped at the very start of the game. The tunic and scarf are battered and worn, with light blue designs on the tunic and mismatched blue and brown arm/leg guards.

Sea Costume
The second outfit can be found in Denial, after formally meeting Nana.

The tunic is blue with bubble and red fish designs alternating on the fabric. Enu's bag and arm/leg guards also turn into a finely woven mesh reminiscent of fish nets.

King Costume
The third  outfit can also be found in Denial, after opening the tower door with the moon puzzle.

Enu's headband and arm/leg guards turn into gold bracers, with his cloak becoming untattered and embroidered and the tunic emblazened with the key design. His hair changes to a slightly redder color. The outfit is highly reminiscent of the Prince from the Keyholes.

Predator Costume
The fourth outfit can be found in Anger, after activating the second windmill.

The tunic becomes a tan color with darker ridges on the skirt. Markings cover Enu's chest and back that highly resemble bird wings. There are white markings on his face and hands that could be interpreted either as paint or vitiligo, and Enu's hair changes to an ashy gray/brown. Due to the naming and the color scheme, this is most likely designed after the Bird.

Sentinel Costume
The fifth outfit can be found in Bargaining, after activating the Sentinel.

The top of the tunic becomes blue with a central Sentinel design, while the circ has an overlapping pattern of the Sentinel's head, and Enu wears white leggings that cause him to look more similar to a Sentinel in appearance. The blue orb that's used to light away the Shades is painted on Enu's chest.

Shade Costume
The sixth and final outfit can be found in Depression, after activating Enu's statue.

The entire tunic becomes black, with purple tentacle-like tendrils reaching from the hem of the skirt. A white circle is painted on the center of the tunic that trails onto Enu's chest, reminiscent of a Shade's face. The rope that ties Enu's arm and leg guards together are now purple as well. The ends of Enu's hair will turn black.

Equipping will cause the Shades to not be afraid of Enu, which is necessary for the achievement Blend-in with the surroundings, which can be achieved by equipping this item at the beginning of Anger before walking between the two groups of Shades on either side of the very first door.
