"The unique sinister trait of the Ravenous Souls is that they actively seek their prey. Unlike other Wraiths they do not haunt a location or a person - instead they hunt their quarry, most usually unwary travellers, quickly devouring their life force and then rushing to find another victim."
The Ravenous Soul has a charge quite easy to avoid once the right timing is learned. His most dangerous tactic is the Zone of Frailty, which can be a problem for melee attacks, since the player suffers more damage inside that area. The best tactic is to lure the Ravenous Soul out of it or use ranged attacks.
