Razorbacks are ranged attackers, similar to the smaller Quill Rats seen in Diablo II. They have a melee attack in close, but are mostly notable for their long range, knife-throwing attacks, as they hunch over and shoot the blades from their backs over considerable distances.Razorbacks have a high pitch chittering noise they make while attacking. Razorbacks are vaguely humanoid and can alternate between being on two legs and being on all fours. According to the Blizzcon vids, razorbacks will charge at opponents when they are injured.
