  • When facing the Elite Shadow Carja and Firestrikers, use the short hallway to prepare your attack and utilize Concentration to aim for weak points.
  • In the room with multiple waves of enemies, use the available coverage to block Deathbringer Gun attacks.
  • Luring enemies into previous rooms can make subsequent encounters easier.
