Sol’s RNG introduced the Aurora Biome with the Eon 1.13 update, also known as the Christmas 2025 update Part 1. Available as a Rare Biome, the Aurora Biome is among the most elusive in the game, with a minuscule chance of it appearing naturally. As is the norm for most Rare Biomes, there are several new Auras with increased roll chance while this Biome is active.
Let’s explore the Aurora Biome in detail and find out what it’s all about.
An overview of the Aurora Biome in Sol’s RNG
The Aurora Biome is classified as a Rare Biome, placing it in the same tier of rarity as Dreamspace, Glitched, and Cyberspace. While the exact spawn chance or condition of this Biome activating naturally is currently unknown, it can be activated manually using the Glowing Snow Globe. This places the control over activating and using this Biome directly in your hands, allowing you to grab its native Auras whenever you wish.
You can get the Glowing Snow Globe from the Christmas Roulette minigame. This wheel-spinning minigame has you spend Tickets to perform a spin, granting you random prizes based on their respective rarities. The Glowing Snow Globe has a minuscule drop rate of 0.2%, so you may have to use several dozen Tickets for even a chance at the reward.
Once you acquire the item, use it by accessing your inventory to cause the Biome shift and make every Aurora Biome-specific Aura available.
