Bonerattler is an Undead Slasher Boss, haunting the Catacombs of Padres Del Fuego. He appears at Level 18-25, and is stationed by a raided Navy encampment. He is the leader of a squad of Undead Raiders encircling an insane Sergeant. He will not be easy to approach without attracting their attack and the entire way to his location is extremely treacherous. File:Bonerattler Map.png
