Wraith

Dragon Age Inquisition
Wraiths are weak ranged enemies in Dragon Age Inquisition. They are introduced as the first ranged enemies encountered in The Wrath of Heaven quest and have attacks that a slow and easily dodged. They drop Dreamer Rags, a creature research item that allows the player to learn more about a creature from a creature research specialist which will allow the creature to be more easily defeated. They may also drop Wisp Essence, a crafting material.

Dragon Age Inquisition Codex Entry
Like wisps, wraiths are sometimes thought to be the remains of spirits or demons that have been destroyed. They cannot shape the Fade around themselves, nor are they capable of mimicking forms they see in the minds of dreamers as many weaker spirits do. Instead, they are the scavengers of beings, feeding on scraps of thought and emotions.
