“Fire is the breaking of bonds. Fire is freedom. We must be swift and thorough in our liberation”
The Purifier Robes are one of the go to exotics for the Sunsinger Warlock due to its exotic perk relying on a self-revive from death. The perk known as Burn Brighter, blinds enemies when Radiance is activated from beyond the grave. However it is quite limited as for it to be functional, you absolutely have to be running Fireborn in your perk tree and if you are killed from even a minor distance, the blinding effect will not take effect and thus be wasted. This exotic is by far PVE oriented due to the higher likelihood that your guardian will become surrounded and swarmed by your enemies. But on that same vein you have to wait for your death and hope that the enemy that eliminated you is close by.
The main standout on the Purifier Robes is the silver bird on the upper chestpiece. It could be any kind of bird of prey such as the Eagle or Hawk due to their associations with power and foresight and even forbidden knowledge. However since this niche exotic is for a Sunsinger, and upon activating Radiance, you gain fiery wings, the mystery bird is most likely the mythical Phoenix.
How to Acquire it?
The Purifier Robes can be gained from an exotic chest engram or purchasing it from Xur if you are lucky enough for him to have it in his inventory.
