Sol's RNG Aura Database — Every Aura & Its Exact Odds

Equinox is the rarest standard-pool aura at 1 in 2,500,000,000 — the hardest Transcendent to roll. Counting biome-locked pools, Monarch is rarer still at 1 in 3,000,000,000, but it only appears during the Corruption or Glitched biomes. Limited event auras have gone as deep as Dream Traveler at 1 in 2,025,012,025 (Christmas 2025).

The Sol's RNG Fandom wiki currently documents 498 auras. 261 of them sit in the standard roll pool across eight rarity tiers (Basic, Epic, Unique, Legendary, Mythic, Exalted, Glorious, Transcendent); the rest are craftable, biome-challenge, event-limited, dev-exclusive, or removed auras.

Transcendent is the tier for auras rarer than 1 in 999,999,999. The five standard-pool Transcendents are Nyctophobia (1/1,011,111,010 in The Limbo), Pixelation (1/1,073,741,824), Luminosity (1/1,200,000,000), Breakthrough (1/1,999,999,999, not obtainable during Null), and Equinox (1/2,500,000,000).

Each biome applies a multiplier that cuts the rarity of its native auras while it's active. Examples straight from the wiki: Divinus drops from 1/32 to 1/6 in Heaven, Lullaby from 1/17,000,000 to 1/1,700,000 during Nighttime, and Pixelation from 1/1,073,741,824 to 1/536,870,912 in Cyberspace. Rolling an aura outside its biome is called a Breakthrough and is harder.

Eight auras are crafted at Jake's Workshop instead of rolled: Eclipse (Legendary), Cell Asteroides and Chromatic : Hyper (Exalted), Atlas : A.T.L.A.S. (Glorious), Abyssal Hunter : Awakened and Matrix : Steampunk (Transcendent), 紅月の災厄 / Calamity of the Crimson Moon (Challenged+), and MasterHand — the only Dimensional-tier aura in the game. Crafting is the only guaranteed route to a top-tier aura.

No — event auras are marked Limited and were only rollable during their event window (Valentines, April Fools, Summer, Halloween, Christmas, Easter, and seasonal Season passes). The wiki lists 169 event auras to date; once an event ends, its auras become unobtainable.

You press the Roll button to randomly receive an aura. Every 10th roll grants double luck automatically. Joining the sol's studio Roblox group unlocks Auto Roll, which rolls continuously and auto-rejoins every 20 minutes to avoid the AFK kick. Quick Roll (100 Robux gamepass) makes rolling instant by skipping the animation. Gear like the Gravitational Device (6x bonus luck), Blessed Tide Gauntlet (3x bonus luck, bonus every 6th roll), and Flesh Device (1.35x bonus luck on every roll) can further boost your odds.

Dimensional is the rarest tier in the game, reserved for auras with a rarity over 1 in 7,500,000,001. Currently the only Dimensional aura is MasterHand, which can only be obtained through crafting at Jake's Workshop — it cannot be rolled.

Each biome discounts the odds of its native auras by a multiplier. Rolling an aura outside its home biome is called a Breakthrough (BT) and is significantly harder. For example, Abyssal Hunter drops from 1/400,000,000 (BT) to 1/100,000,000 during Rainy weather. Rare biomes like Glitched, Cyberspace, Singularity, and Dreamspace gate some of the rarest auras in the game — Monarch (1/3,000,000,000) only appears in Corruption or Glitched.

A Breakthrough (BT) happens when you roll a biome-native aura while that biome is not active. Breakthrough odds are always higher (harder) than the native odds — each biome has its own multiplier. For example, Windy biome auras have a 3x BT multiplier, meaning their odds triple outside Windy weather. The aura named Breakthrough is itself a Transcendent at 1/1,999,999,999, but it cannot be rolled during the Null biome.
