Sol’s RNG Aura Tier List: Rarest Auras Ranked
Which auras are actually the rarest, and where do you roll them?
Sol's RNG is a pure luck game with more than 400 auras, and the whole point is chasing rarer and rarer rolls. So a tier list here is not about opinions, it is about the actual odds.
That is exactly how we built this one. Every aura below is ranked by its real rarity straight from the game's own data, and we show the biome you need to be in to roll it.
New here? Our Sol's RNG wiki covers the basics, and the Sol's RNG codes page lists free luck boosts and potions.
The Quick Answer
The rarest aura you can actually roll is Monarch at 1 in 3 billion, and it only appears in the Corruption or Glitched biome. But the smartest aura to chase is Ascendant, because rolling it in Heaven cuts its odds from 1 in 935 million all the way to 1 in 187 million.
Rolling for auras is only half of it. Gear recipes are paid for in the auras you roll, and our guide to all 44 gears shows the best right hand, left hand and pocket gear to wear together, worth +1,850% luck.
How Aura Rarity Actually Works
Sol's RNG does not use a made-up S to D ranking. It has a real rarity ladder built into the game, and every aura sits on it based on its odds. Three things decide what you can roll.
Rarity is just the odds. Every aura has a fixed chance, like 1 in 3,000,000,000. The rarer the number, the higher the band it sits in. That is the real tier list.
Biomes change everything. Some auras only exist in one biome, and others become far more likely there. Rolling in the wrong biome can make an aura literally impossible to get.
Luck multiplies your odds. Potions, gear, and luck items stack to improve every roll. Save your strongest boosts for when a rare biome is active.
The Real Rarity Ladder
This is the game's own rarity system, with the exact odds for every band. Use it to know where an aura really sits.
| Band | Odds range | What it means |
|---|---|---|
| Basic | 1 in 1 to 1 in 999 | Everyday rolls. You will see hundreds of these. |
| Epic | 1 in 1,000 to 1 in 9,999 | The first auras that feel like something. |
| Unique | 1 in 10,000 to 1 in 99,998 | Includes the 1-star aura. |
| Legendary | 1 in 99,999 to 1 in 999,998 | Includes the 2-star aura. |
| Mythic | 1 in 999,999 to 1 in 9,999,999 | Includes the 3-star aura. A real milestone. |
| Exalted | 1 in 10,000,000 to 1 in 99,999,998 | Serious luck territory. |
| Glorious | 1 in 99,999,999 to 1 in 999,999,998 | The realistic endgame chase. |
| Transcendent | 1 in 999,999,999 to 1 in 7,500,000,000 | The rarest normal rolls in the game. |
| Dimensional | 1 in 7,500,000,001 to 1 in 12,500,000,000 | The absolute top of the ladder. |
| Challenged / Challenged+ | Special conditions only | Cannot be rolled normally. You must meet certain conditions. |
| Event | Limited time only | Available during a specific occasion, like Christmas or Easter. |
| Unobtainable / Dev | Not rollable | Retired auras or developer-only. No longer available to players. |
Sol's RNG Aura Tier List
Here is the tier list, mapped onto those real rarity bands so the rankings actually mean something.
| Tier | Rarity band | Example auras | What to know |
|---|---|---|---|
| S | Transcendent and above (1 in 1 billion or rarer) | Monarch, Equinox, Dream Catcher, Breakthrough, Astraios, Leviathan, Luminosity | The rarest auras you can actually roll. Most need a specific biome, and you will likely never see one without heavy luck stacking. |
| A | Glorious (1 in 100 million to 1 in 1 billion) | Ascendant, Dreamscape, Aegis, Sovereign, Eisveil, Poseidon | The realistic endgame chase. Ascendant is the smart target here because Heaven cuts its odds five times over. |
| B | Exalted (1 in 10 million to 1 in 100 million) | Chromatic: Genesis, Nucleus, HellBound, Virtual: WorldWide, Runic: Wilt | Serious luck territory and a great mid-game goal. Very reachable once you are stacking potions and gear. |
| C | Mythic (1 in 1 million to 1 in 10 million) | Amethyst, Stargazer, Nihility, Helios, Jade, Harnessed | Your first real milestone. Hitting any Mythic means your luck setup is finally working. |
| D | Legendary and below (1 in 100 thousand to 1 in 1 million) | Kyawthuite, Verdict, Warlock, Prowler, Clockwork, Undead: Devil | Early auras. Nice to see at first, but you will roll past these quickly once your luck goes up. |
The Rarest Auras You Can Still Roll
These are the rarest auras currently obtainable, with their exact odds and the biome you need. Note how many are biome-locked.
| Aura | Odds | Where you can roll it |
|---|---|---|
| Monarch | 1 in 3,000,000,000 | Only rolls in CORRUPTION or GLITCHED. |
| Equinox | 1 in 2,500,000,000 | Rolls anywhere. No biome needed. |
| Dream Catcher | 1 in 2,222,222,222 | Only rolls during NIGHTTIME. |
| Breakthrough | 1 in 1,999,999,999 | Rolls anywhere except during NULL. |
| Astraios | 1 in 1,750,000,000 | Only rolls in SINGULARITY. |
| Leviathan | 1 in 1,730,400,000 | Only rolls in RAINY or GLITCHED. |
| Luminosity | 1 in 1,200,000,000 | Rolls anywhere. No biome needed. |
| Pixelation | 1 in 1,073,741,824 | Twice as likely in CYBERSPACE (1 in 536,870,912). |
| Nyctophobia | 1 in 1,011,111,010 | Rolls in THE LIMBO. |
| Ascendant | 1 in 935,000,000 | Five times more likely in HEAVEN (1 in 187,000,000). |
| Dreamscape | 1 in 850,000,000 | Rolls in THE LIMBO. |
| Aegis | 1 in 825,000,000 | Rolls anywhere. No biome needed. |
Rare Auras You Can No Longer Roll
Here is something most aura lists get wrong. Several of the "rarest auras in the game" you will see ranked online are limited event auras that are no longer obtainable. Chasing them is a waste of luck potions.
| Aura | Odds | Why you cannot get it |
|---|---|---|
| You Are An Idiot | 1 in 2,500,000,000 | April Fools 2026 event |
| Dream Traveler | 1 in 2,025,012,025 | Christmas 2025 event |
| Sky Festival | 1 in 2,000,000,000 | Easter 2026 event |
| Y.O.L.K.E.G.G. | 1 in 1,790,909,090 | Easter 2026 event |
| Winter Garden | 1 in 1,450,012,025 | Christmas 2025 event |
| Erebus | 1 in 1,200,000,000 | Halloween 2025 event |
| Lamenthyr | 1 in 1,000,000,000 | Halloween 2025 event |
They may return if the event comes back around, but right now they cannot be rolled. Every aura in the table above this one, by contrast, is still live.
Smart Rolling: Get More From Every Roll
Luck is random, but how you spend it is not. Here is how to actually improve your chances.
- Roll in the right biome. This is the biggest lever in the game. Ascendant is five times more likely in Heaven, and Pixelation is twice as likely in Cyberspace. Some auras, like Monarch and Astraios, only exist in one biome at all.
- Save your best potions for rare biomes. Burning your strongest luck boosts during a normal biome wastes them. Hold them until a rare biome appears, then stack everything.
- Climb one band at a time. Go Mythic, then Exalted, then Glorious. Aiming straight for a Transcendent aura without a huge luck setup is just wishful thinking.
- Do not chase retired auras. Check the table above. If it was an event aura, no amount of luck will roll it right now.
- Stock up on free boosts. The Sol's RNG codes page hands out potions and luck items that make every roll count.
What to Chase Right Now
| Your goal | Target | Why |
|---|---|---|
| Rarest you can actually roll | Monarch | 1 in 3 billion, and only in Corruption or Glitched. |
| Best realistic chase | Ascendant | 1 in 187 million in Heaven instead of 1 in 935 million. |
| Best early goal | Any Mythic aura | 1 in 1 million or better. Your first real milestone. |
| Best mid-game goal | Any Exalted aura | 1 in 10 million or better, very doable with potions. |
| Biome that helps most | Heaven | Cuts Ascendant's odds five times over. |
| What to ignore | Limited event auras | You simply cannot roll them anymore. |
Sol's RNG now has more than 400 auras and keeps adding more with every update and event, including the current Boss Raid Hell content. New auras can shift the top of the ladder, so we keep this page updated with the real odds. Grab free potions on the Sol's RNG codes page before your next big roll session.
Tips for Better Rolls
- Watch for biome changes and be ready. A rare biome is your best window all session.
- Craft and equip luck gear before you start rolling, not halfway through.
- Remember that odds do not have memory. A thousand bad rolls does not make the next one luckier.
- Claim free luck items from the Sol's RNG codes page.
Frequently Asked Questions
Quick answers from this guide.
01What is the rarest aura in Sol's RNG?
Monarch, at 1 in 3,000,000,000. It only rolls in the Corruption or Glitched biome, so you cannot get it anywhere else.
02What is the best aura to actually chase?
Ascendant. It is 1 in 935 million normally, but only 1 in 187 million if you roll it in Heaven, which makes it far more realistic than the Transcendent auras.
03How do biomes affect auras?
Some auras only roll inside a specific biome, and others get much better odds there. Rolling in the wrong biome can make an aura impossible to obtain.
04How do I improve my luck?
Stack luck potions, gear, and items, and save your strongest boosts for when a rare biome is active. That combination is what actually moves your odds.
05Why can't I roll some of the rarest auras I see online?
Because many of them are limited event auras from Christmas, Easter, Halloween, or April Fools, and they are no longer obtainable. See our retired-aura table above.
06Does Sol's RNG have codes?
Yes. Check our Sol's RNG codes page for the current list. Codes usually give free luck potions and boosts.
