Nautilus : Lost

If Nautilus is about the chain, Nautilus : Lost is about being lost. It is the Mythic mutation of Nautilus, added in Eon 1-6 at 1 in 7,700,000 with no biome shortcut, so about 7.7 million rolls at 1x luck or 770,000 with 10x. The creator is bargkan. Curiously, the same figure is the native chance of Melodic : Serenade in Nighttime, though the two are unrelated.

According to the Sol's RNG Wiki it keeps the cobalt chain to the middle of the torso and the smaller cross-pattern chains, but adds a bright glow on the forehead as a mystical focal point and chains holding both hands. On top of the player three beams of light point to the ground and shed bubble particles, and beneath them is a black puddle effect similar to Abyssal Hunter. The walking animation makes the player look like they are swimming.

The opening cutscene starts black, with a jingle and wind that last throughout, white fog at the bottom and indigo particles in the centre. The text repeats the parent aura's line about a small shout from the depths of the abyss.
