Bioluminescent

Bioluminescent was never in the roll pool. The Sol's RNG Wiki says it was sold by the NPC Lime for 200 Pearl Blue Clams during the Summer 2025 event (Eon 1-6), added on 5 July 2025, and the event has ended, so it is unobtainable now. No odds exist, and the wiki notes that the aura had a roll cutscene despite not being rollable, which was removed in the Summer Part 2 update. It is credited to Lynoxiouszxcs, meltedwaffled, TRMG_YT and omnivoore.

What stands out is the ability. Rain of Spear lets the user mark an area in front of them, summoning a clef sign that charges up and explodes into a rain of water spears. The wiki gives the damage as 2.5 per spear, eighteen times in the area, which adds up to 45 if everything lands.

The look is a deep sea at night. The player floats on a blue celestial floor with two glowing jellyfish behind them, dark blue-purple fog rises with shining particles, pink and blue fish circle along the floor, and a glowing blue halo wraps the torso.
