Sol's RNG has roughly 339 auras as of July 2026, with drop rates spanning from 1 in 2 all the way to 1 in 3 billion. That's an absurd range, and it means not all auras are created equal — not even close. This tier list ranks the most notable auras from S Tier down to D Tier based on rarity, practical value in raids, and how much they're worth in the trading scene.
We've factored in biome-dependent drop rates, gear multipliers, and real community trading data to build these rankings. Whether you're AFK rolling for your next flex piece or trying to figure out what's actually worth chasing, this list will save you time. You can play Sol's RNG directly on Roblox (Place ID: 15532962292).
S Tier — Best Auras in Sol's RNG
S Tier is reserved for the auras that most players will never see. These are Transcendent and Glorious rarity auras with drop rates starting at 1 in 1 billion and going up to 1 in 3 billion. Owning any of these is a statement — they're the rarest items in the entire game and command massive trade value.
Monarch (1 in 3,000,000,000)
Monarch sits alone at the top. Its 1 in 3 billion drop rate makes it the single rarest aura in Sol's RNG, and it's not particularly close. Monarch carries the Challenged rarity tag, which means you can't just roll it through normal gameplay. You need to meet a specific in-game condition before the aura even enters your drop pool. Most players will never roll Monarch in their lifetime of playing, which is exactly what makes it the ultimate flex.
In terms of trade value, Monarch is essentially priceless. The handful of confirmed Monarch owners can name their price, and the demand never drops. If you're serious about chasing it, stack every luck multiplier available — VIP pass (1.2x), end-game gear, and favorable biomes — and prepare for a very long grind.
Nyctophobia (1 in 1,011,000,000)
Nyctophobia is a Transcendent aura with a base drop rate of 1 in 1.011 billion. The catch? It only drops during the Limbo biome. That biome doesn't show up often, so your actual window for rolling Nyctophobia is extremely narrow. You're fighting two layers of RNG: first the biome has to spawn, then you need to hit the 1 in 1.011 billion roll while it's active.
This biome dependency is what separates Nyctophobia from theoretical drop rates. On paper, other auras might look comparable. In practice, the Limbo requirement makes Nyctophobia one of the hardest auras to obtain in the game. It's a top-tier trophy piece with real bragging rights.
Pixelation (1 in 1,073,000,000)
Pixelation has a base drop rate of 1 in 1.073 billion, but here's where it gets interesting. During the Cyberspace biome, that rate drops to roughly 1 in 536 million — nearly doubling your odds. That's still astronomically rare, but it makes Pixelation slightly more accessible than other Transcendent auras if you time your rolls correctly.
Smart players track biome rotations and go hard on rolling when Cyberspace is active. The difference between 1 in 1.073 billion and 1 in 536 million is massive over thousands of rolls. If you're targeting a Transcendent aura and want the "best" odds (relatively speaking), Pixelation during Cyberspace is your most realistic shot.
Luminosity (Transcendent)
Luminosity is another Transcendent-tier aura with a drop rate north of 1 in 1 billion. It's one of the most visually striking auras in Sol's RNG, and its rarity puts it firmly in the same conversation as Nyctophobia and Pixelation. The visual effect alone makes it a highly sought-after trade piece, and confirmed owners are few and far between.
Breakthrough (Transcendent)
Breakthrough rounds out the Transcendent tier with similarly brutal drop rates. Like the other auras in this category, getting Breakthrough requires an enormous amount of rolls, optimal gear, and ideally a biome multiplier working in your favor. It's not something you farm casually — it's something you grind for over weeks or months.
Equinox (Transcendent)
Equinox completes our S Tier lineup. As a Transcendent aura, it shares the same 1 in 1 billion+ rarity class that defines this tier. Equinox carries strong trade value and remains one of the most requested auras in trading servers. If you roll one, you've essentially won the Sol's RNG lottery.
A Tier — Excellent Auras
A Tier auras have drop rates in the hundreds of millions. They're still incredibly rare — most players won't roll these without serious grinding — but they're a step below the billion-plus rates of S Tier. These are the auras that dedicated players can realistically chase with enough time and the right setup.
Glorious Auras (1 in 100M–999M range)
The Glorious rarity category contains several auras that sit in the 1 in 100 million to 1 in 999 million range. These are the auras that experienced players target as their primary goals. They're rare enough to be impressive but obtainable enough that you won't feel like you're chasing a ghost. With Starfall biome (5x) active and maxed-out gear, your effective drop rates improve substantially.
Biome-Conditional Rares
Several A Tier auras have their drop rates tied to specific biome conditions, similar to Nyctophobia in S Tier but with better base odds. These auras require you to track biome cycles and time your grinding sessions accordingly. The players who log the most A Tier auras are almost always the ones paying close attention to which biome is currently active. Check our Sol's RNG codes page for any active codes that might boost your rolls.
Raid-Meta Auras
Some A Tier auras earn their placement through raw utility rather than just rarity. Velvet is the standout example — it's ranked S+ by the community specifically for boss raids. Velvet heals 30 HP in a large area every 9 seconds, which makes it the best support aura for keeping your raid team alive. You might have rarer auras, but Velvet will get you invited to more raid groups than almost anything else.
B Tier — Good Auras
B Tier covers Exalted rarity, higher-end Mythical auras, and select event-exclusive auras. Drop rates here typically range from 1 in 1 million to 1 in 99 million. These auras are genuinely rare — the average player won't roll one without dedicated grinding — but they're common enough that you'll see them in most active trading servers.
Event-exclusive auras deserve special mention. Some of these were only available during limited-time events and can't be rolled anymore, which gives them inflated trade value regardless of their original drop rate. If you have an event aura from a past season, check current trading values before letting it go — scarcity from unavailability can push a B Tier aura's trade value into A Tier territory.
For players still progressing through Sol's RNG, B Tier auras represent strong milestones. Rolling your first Exalted aura feels genuinely exciting, and these auras are impressive enough to show off without being so rare that nobody believes you actually rolled them legitimately.
C Tier — Average Auras
C Tier is home to the more common Mythical rarity auras. Drop rates here land somewhere in the 1 in 100,000 to 1 in 999,999 range. You'll still need some luck and decent gear to roll these, but they're realistic targets for players who haven't maxed out their luck multipliers yet.
Mythical auras make solid stepping stones in your collection. They look noticeably better than anything in Legendary or below, and they hold enough trade value to be useful in deals. Most active players will accumulate a handful of C Tier auras within their first few weeks of serious grinding. They're not going to make anyone jealous in a trading server, but they prove you're putting in the hours.
If you're still running early-game gear, C Tier auras should be your first milestone. Get your Luck Glove upgraded and keep rolling — you'll start seeing Mythical drops more regularly as your luck multiplier climbs. Our Sol's RNG free Robux guide covers how to earn Robux for gear upgrades without spending real money.
D Tier — Common Auras
D Tier covers Legendary rarity auras with drop rates between 1 in 99,999 and 1 in 850,000. These are the auras that fill out most players' collections early on. They're not particularly rare, and trade value is minimal, but they're still a step above the Common and Uncommon auras you'll roll constantly.
Don't dismiss D Tier entirely, though. Some Legendary auras have decent visual effects, and they're useful for completing collection milestones that unlock bonuses. New players should focus on rolling through this tier quickly by upgrading from the Luck Glove to the Frozen Gauntlet as soon as possible — the improved luck multiplier starts pulling you into C Tier territory much faster.

How We Ranked These Auras
Three factors drove these rankings: drop rate rarity, practical utility (especially in boss raids), and trade value as of July 2026. Drop rates were pulled from the game's documented probabilities, and we cross-referenced them with community data from active trading servers and wiki contributors.
Rarity alone doesn't determine placement. An aura with a 1 in 500 million drop rate that has no raid utility and limited visual appeal won't necessarily outrank a 1 in 100 million aura that's meta-defining for raids. Velvet is the clearest example — it earns A Tier placement through its irreplaceable healing role in boss content, not just its drop rate.
We also accounted for biome conditions. Auras that require specific biomes to roll effectively have their difficulty inflated beyond what the raw drop rate suggests. Nyctophobia's 1 in 1.011 billion rate is already brutal, but the Limbo biome requirement makes it functionally even rarer. Conversely, Pixelation gets a slight accessibility bump because Cyberspace cuts its effective rate nearly in half.
Gear progression matters here too. The path from Luck Glove to Frozen Gauntlet to Subzero to Galactic to Heavenly or Unfathomable dramatically changes which tiers are realistic targets. A player with end-game gear and VIP+ (350 Robux) has meaningfully better odds at every tier than someone running early-game equipment.

Frequently Asked Questions
Monarch is the rarest aura in Sol's RNG as of July 2026, with a drop rate of 1 in 3,000,000,000 (3 billion). It's classified as Challenged rarity, meaning you also need to meet a specific in-game condition to roll it. No other aura comes close to this drop rate.
Sol's RNG currently has approximately 339 auras as of July 2026. They range from Common auras with a 1 in 2 drop rate all the way up to Challenged rarity auras at 1 in 3 billion. New auras are added regularly through updates and limited-time events.
Yes, biomes have a major impact on drop rates. Starfall gives a 5x luck multiplier, Rainy gives 4x, and Windy gives 3x. Some auras like Nyctophobia can only drop during specific biomes (Limbo in this case). The Null and Corruption biomes offer the highest multipliers but are extremely rare to encounter.
The standard VIP pass costs 249 Robux and gives a 1.2x luck multiplier that stacks with biome bonuses and gear. VIP+ costs 350 Robux with additional perks. If you're actively grinding for rare auras, the 1.2x multiplier adds up over thousands of rolls and is generally considered a solid investment for serious players.
The optimal gear progression is Luck Glove, then Frozen Gauntlet, Subzero, Galactic, and finally Heavenly or Unfathomable at end-game. Each upgrade increases your luck multiplier, which directly improves your chances of rolling higher-rarity auras. Combine gear bonuses with biome multipliers and VIP for the best possible rates.
Velvet is widely considered the best raid aura, ranked S+ by the community for its healing ability. It heals 30 HP in a large area every 9 seconds, making it invaluable for keeping your team alive during boss fights. For DPS, look at Transcendent-tier auras, but Velvet's support role is often more impactful for raid success.
