The Temple Ruins Version 2.3.1

ARRGHUS
- Location: Swamp Palace
  Effective Weapons: Hookshot, Sword
  
  Attacks: During the first half of the fight, Arrghus will occasionally make the small ”arrghi” fly around him. If they hit you damage will be done. During the second half, Arrghus will flee to the ceiling and then drop on you before skittering on top of the water.
  
  Strategy: Equip the Hookshot and begin shooting it at the small ”arrghi”. When you grab one, immediately swipe at it with your sword a few
  times to defeat it. Then, continue grabbing them until you have defeated them all. When all of the ”arrghi” are gone, Arrghus will flee to the
  ceiling and try to smash you. When you see his shadow, move out of the way to avoid being hit. Then, attack him with your sword to make
  him flee to the ceiling once more. He will continue to try and smash you until he is defeated.
  
  Other Tips:
  - When you begin attacking Arrghus with your sword, it is good idea to use Spin Attacks. It will make the fight go quicker.
