Crafted at a Tinkerer's Workshop by combining Diving Gear with a Jellyfish Necklace dropped by Blue or Pink Jellyfish. This accessory greatly extends underwater breath duration, grants the ability to swim upwards through liquid bodies, and emits a soft ambient glow that brightens considerably when the character is submerged in water or honey pools.
Deep ocean expeditions and arctic upgrades
Essential for exploring the ocean seabed, sunken chests, and flooded cavern networks without relying on Gills Potions or breathing reeds. It subsequently combines with Ice Skates to produce Arctic Diving Gear, adding icy footing stability. While aquatic mounts like the Cute Fishron outpace it in late Hardmode, this gear remains the premier early exploration solution for underwater mining. Reforging to Warding provides 4 defense for survival against ocean predators.
Trivia
The underwater glow changes color depending on whether the character wears vanity dyes in the accessory slot.
The extended breath timer reduces underwater breath loss to one fifth of normal speed.
