They are described as being fast, agile and competent at fighting with very high morale but also afraid of being hurt? I’ve never seen one fight but they frequently spawn in near the corpses of civilians and when attacked by either me or monsters they run 100% of the time and avoid combat at all cost.
So are they competent fighters with high morale or cowards who use their agility to flee? Why do they spawn in near civilian corpses to imply they were involved in slaying them but run from the comparatively slow and weak zombies, including laughably easy monsters like crawling zombies?
These guys have a high melee and dodge skill they should make you think twice about bopping them for their butchery goodies. I mean look at their description
This is some form of eldritch monstrosity; an uncouth black being with smooth, oily, skin and unpleasant horns that curve inward toward each other. Tall and thin, the shadows cling unnaturally to its vaguely defined humanoid form as it shuffles along, its hands twitching and spasming so rapidly as to appear a little more than a black blur of claws. Gazing upon its disturbing form fills you with an unspeakable terror.
