Cataclysmic

Cataclysmic is the second cheapest of Jack The Pumpkin's four Halloween 2026 auras: 17,250 Hallow Points, between Cruor at 15,000 and Acropolis at 20,000. Like the others it is an Event-tier aura from Eon 1-31 that you buy instead of rolling. Hallow Points come from Jack's bounty board, where three biome-based orbs appear every 24 hours.

Its history is unusually well documented. The wiki says it was based on an old whitelisted aura called OBLIVION, made by idkaple and valkziel, and warns that it is not the in-game aura Oblivion. The creators are khxlla, onlyyxyyz and Vk5278, with the concept by idkaple. It shares its song with Godslayer, Devel Sullivan's Dream Pursuer, and its name is unrelated to the Geometry Dash level Cataclysm.

The oddest detail is visual: when Cataclysmic is equipped, a Yoisaki Kanade plushie appears inside the player's body, and the wiki keeps a screenshot of it. The in-game description is empty and the appearance section still says TBA, so nothing more is documented. In the wiki's aura order it follows Embercrypt.
