  • 10 to 20 Detonating Bubbles appear from the boss’ mouth and travel in the player’s direction
  • Liquid blobs fall from the boss’ fins, which will spawn Sharknados that fire Sharkron missiles
When Duke Fishron’s health falls below 50%, its skin darkens, and its eyes glow. This new appearance indicates the battle’s second phase. In this stage, the boss’ attacks are:
  • The Detonating Bubbles leave additional bubbles behind
  • Only one liquid blob falls from its fins but it will summon a giant Cthulhunado that fires twice as many Sharkron missiles
