The serpent man and the human NPC’s have fought each other for a long time. But now the hatred has turned man against man and they are all fighting against each other. At first I thought it was faction related but it appears to be something else may profession or just pure hatred for anyone that isn’t already in the same group. All NPC’s with little exception will fight and kill each other.
Conan is now a Battle royale game for NPCs 
Thank you, we’ve sent note to the developers regarding these NPCs’ behavior.
