"The most ravenous of alla Wraiths are called Tortured Souls, not because they suffer the anguish of mortals but because they are the epitomes of accumulated fear, pain and despair. Feeding upon the souls of its doomed victims, the Tortured Soul would eventually collect all sort of nightmares which it lets out in agonizing wails of anguish."
The Tortured Soul releases a cone-shaped scream to inflict damage and a Zone of Bleeding that drops health over time.
The better strategy, is to stay out of the Cone Attack area, to lure the Tortured Soul out of the Zone of Bleeding.
