About Pump
Halloween 2024 gave Sol's RNG its pumpkin, and Pump is the original of the pair. The Sol's RNG Wiki describes a pumpkin that hides the player's face and glows yellow from inside with flame-like particles, a pale yellow face that flickers on the chest, and a portal-like circle writhing under the feet, similar to Archangel. It was added in Eon 1-1.
Two things made it unusual. First, it could not be rolled through Breakthrough: it only came up in the Pumpkin Moon biome. Second, its odds were forgiving for a limited aura, 1 in 200,000, around 200,000 rolls at 1x luck or 20,000 at 10x, so a player who stayed through the biome had a real shot at it. The wiki's unobtainable notice carries the date 02/08/2025, after the event ended, and it is now an ended Event tier aura. Pump has a later mutation, Pump : Trickster, that returned for Halloween 2025. The credited creator is 53_Axis.
