The Queen Jellyfish (Diverless)

The Queen Jellyfish is a Pre-Hardmode boss that must be fought above the ocean waters. It is considered a biome-specific boss for the Ocean biome.

While The Queen Jellyfish is alive, the vanilla track Boss 1 will play.

Spawn[ | ]

The Queen Jellyfish does not spawn on its own, and requires the player to summon it with a Jellyfish Resonator. It can only be summoned while the player is near the Ocean during the day.

Behavior[ | ]

The Queen Jellyfish hovers slightly above the player, launching bubbles to attack the player. It summons Royal Jellies to attack the player and uses its tentacles to attack in Expert Mode.

Attacks[ | ]

  • The Queen Jellyfish will shoot a large slow moving bubble that deals moderate damage and inflicts the Bubbled debuff; flinging the player high into the air.
  • The Queen Jellyfish stops and creates a stationary cyclone that sucks the player in; contact with the cyclone can kill the player in a few seconds.

In Expert Mode

  • Upon reaching 45% health, The Queen Jellyfish will begin extending tentacles that deal high contact damage.

Summons[ | ]

Aftermath[ | ]

  • The Diverman will spawn immediately from The Queen Jellyfish upon defeating it for the first time. He can then move in if provided suitable housing.
  • Once defeated, the Cobbler will start selling Water Walking Boots.

Notes[ | ]

  • After defeating The Queen Jellyfish once, subsequent appearances of the boss do not have the Diverman NPC inside its head, and subsequent defeats of the boss will not spawn additional Divermen.
  • The Queen Jellyfish will take massively increased damage from melee strikes.
