Embercrypt

Embercrypt rolls at 1 in 9,700,000 in Pumpkin Moon, and the wiki lists Glitched as the only other place it can appear. Of the five Halloween 2026 auras native to Pumpkin Moon it is the second rarest, behind Cauldron at 1 in 24,000,000. Among the 420 auras with a recorded chance it ranks 216th, and 92nd of 135 in the Event tier.

The description sets the scene underground: a labyrinth of winding, twisting corridors where the air is foul and the crypt reeks of decay under a night-sky moon. The appearance matches. An orange full moon shines above the player, dark orange auras surround the area and the floor, and several tombs and gravestones stand on platforms beside the player. Two of those platforms connect to the moon by an orange beam, and light orange and white particles keep rising from the ground.

Credits are MrInsano80 and the_sillywolfy for the creation, Lunar Mare by xi and Sakuzyo for the music, and Playfair Display for the font. It was added in Eon 1-31 on 31 October 2026, and the wiki places Cataclysmic directly after it in the aura order.
