Reaper

Reaper is built around an eye. The Sol's RNG Wiki places a giant dark crown-like halo at the top of the aura, with a red whirlpool around it and an eye-shaped structure at the center that sends red beam-like particles down to the player. The player floats slightly above the floor with a huge red scythe in the right arm and the left hand on the hip, while two red screens on the sides show animated eyes that blink and look around in front of a background of moving red and white lanes. A red whirlpool with a four-pointed star sits under the player.

It was added in Eon 1-9 as part of the Halloween 2025 event, and it rolled exclusively in the Blood Rain or Glitched biomes with a chance of 1 in 66,000,000. At 1x luck that is about 66,000,000 rolls, or 6,600,000 at 10x. The wiki's notice dated 11/30/2025 says the event has ended, so Reaper is unobtainable now. The song is SILENCE IS A LIE by justdev, and five creators are credited, including goldiegamer1234 and 7rv1x.
