Sol's RNG Singularity: Biome, Catalyst & Every Aura's Odds

Last Verified: May 4, 2026. Aura names and drop odds sourced from the Sol's RNG Fandom wiki (sol-rng.fandom.com/wiki/Auras), community-verified drop data from the Sol's RNG Discord, and Sportskeeda's Singularity update coverage. 9 of the 13 new auras have confirmed community-verified names and rates. The remaining 4 are unconfirmed — we will not publish guesses for those names or odds.

The Singularity update dropped on April 25, and nine days later community data is solid on 9 of the 13 new auras. Exact drop rates for high-tier auras usually take a few days of collective farming to pin down, which is why our Sol's RNG Singularity Update overview on April 26 left the names and odds out.

Here they are: every confirmed name, tier and exact odds, plus the full Singularity Catalyst crafting recipe and what each tier realistically means for your grind.

Four aura names remain unconfirmed. We know from the update notes that 13 auras were added (1 Challenged+, 3 Glorious, 2 Exalted, 5 Mythic, 1 Basic, 1 Craftable). Of those, the 4 missing names likely fall in the Basic and remaining Glorious slots.

Until they're verified, check the Fandom aura wiki for the latest community verification on those.

Breakdown by Tier

Challenged+ — Astraios (1 in 1,750,000,000)

Astraios is the flagship aura of the Singularity update and, at 1 in 1.75 billion, it's the rarest rollable aura in the game at Eon 1.20. It's exclusive to the Singularity Biome, so you can only roll it during an active Singularity window, and that window needs a Singularity Catalyst to open.

To put the odds in context: with maximum Luck stacking inside the Singularity Biome (1.1x Total Luck from the biome, plus potions and event bonuses), you're still looking at a multi-billion-roll proposition for a single Astraios.

Anyone wearing one has put in an absurd volume of farming time, not just hit one lucky session. The Challenged+ tier sits above even the rarest Legendary auras; most veteran players will never land one.

Glorious — Projection (1 in 197,000,000)

Projection is the only confirmed Glorious-tier aura from Eon 1.20's 13 additions (2 more Glorious auras are unconfirmed). At 1 in 197 million, it's still deep-endgame territory and exclusive to the Singularity Biome. The two unconfirmed Glorious auras likely have comparable odds.

Exalted — Centurion & Oculus (1 in 23–25M)

Oculus (1 in 23,233,340) is technically a touch more common than Centurion (1 in 25,000,000), but at that scale the gap is noise. Both are Singularity Biome exclusives, and both need sustained endgame farming inside the Singularity window.

The Exalted tier remains a long-term grind for most players but lands in the realm of "achievable with consistent effort" for accounts farming multiple Catalyst windows per week.

Mythic — Pleiades, Pulsar, Constella, Vega

The four confirmed Mythic auras represent the most realistic targets for mid-to-high-level players:

Pleiades, Pulsar, and Constella are all rollable without the Singularity Biome. At 1 in 65,000–86,000, a player running consistent luck stacks can reasonably target these. They're in the same odds neighborhood as late-stage Legendary auras from previous eras.

Vega at 1 in 2.58 million is Singularity-exclusive and is the stepping stone from accessible Mythics to the deep-endgame tiers above.

Craftable — Master-Hand (1,250,000,000 collected stat)

Master-Hand is unique in Eon 1.20: it doesn't roll from probability. Instead, it's unlocked by reaching a 1,250,000,000 total collected stat milestone. This is a long-term account progression gate rather than an RNG gamble. If you've been farming actively since the Singularity update dropped, you're already accumulating toward this milestone, chasing it or not.

The upside of a crafted/milestone aura: it's guaranteed with enough time investment, unlike the Challenged+ and Glorious auras that remain genuinely uncertain regardless of time spent. For players who dislike pure RNG walls, Master-Hand is the Singularity update's most deterministic high-tier reward.

Singularity Catalyst — Full Crafting Recipe

The Singularity Biome requires a Singularity Catalyst to activate. Each Catalyst gives you a 20-minute Singularity window. Here's the full recipe:

The single Gargantua (1 in 430 million) is the real gate. The 30 Comets look scary on paper, but they add up to only ~3.6M expected rolls, a fraction of the Gargantua requirement.

The Catalyst is deliberately designed as a deep-endgame item; acquiring one from scratch requires either extraordinary RNG or sustained farming across hundreds of millions of rolls. Realistically, most players will trade for Catalyst access rather than craft from scratch.

Starfall note: Gargantua, Galaxy, and Comet moved from Starfall Biome to Singularity Biome exclusives in Eon 1.20. If you were farming Starfall specifically for these, update your routing. They no longer drop there.

---

Singularity Biome — What You Get During the Window

Once you activate a Singularity Catalyst, the 20-minute Singularity Biome window provides:

• 1.1x Total Luck multiplier: stacks multiplicatively with potions, event bonuses, and passive luck buffs. This isn't a small bonus at scale; for players already running heavy luck stacks, 1.1x compounds meaningfully on top of existing multipliers.
• Access to all Singularity-exclusive auras: Astraios, Projection, Centurion, Oculus, and Vega only drop during this window
• Access to Gargantua, Galaxy, and Comet: formerly Starfall, now Singularity-exclusive

Each 20-minute window is a rare resource. Maximize it by pre-stacking potions and any event luck bonuses before activating the Catalyst. Activating mid-buff-session wastes part of the window on setup time.

Starfall Biome Changes Post-Singularity

Three auras moved out of Starfall in Eon 1.20: Gargantua, Galaxy, and Comet are now Singularity-exclusive. Starfall still exists as a biome but its aura pool narrowed. If your Starfall farming strategy was built around any of these three, you need to pivot to Singularity access.

Starfall remains worth farming for its remaining exclusive auras. It's not deprecated, just changed. The shift creates a two-track endgame: Starfall for its specific pool, Singularity for the new content and the three moved auras.

Grind Strategy by Player Level

Mid-Game (not yet farming Starfall)

The Singularity content isn't your current priority. The three rollable Mythics (Pleiades, Pulsar, Constella) are achievable without Biome access and represent a genuine upgrade target at this tier. Focus on luck stacking and consistent rolling; these three auras will appear in your normal roll sessions.

High-Level (farming Starfall, reaching Legendary auras)

Start accumulating the Comet and Galaxy components passively. These drop in Singularity now, so you'll need Catalyst access eventually, but trading for a short Singularity window is an option before you can craft your own Catalyst. Prioritize Vega (1 in 2.58M inside Singularity) as your first Singularity target; it's the entry point into the update's upper tier.

End-Game (crafting Catalysts, farming Exalted+)

Run Singularity windows with maximum luck stacking. Centurion and Oculus (Exalted, ~1 in 23–25M) are your realistic targets. Master-Hand is a milestone target that accumulates naturally alongside all other farming. Astraios and Projection are aspirational unless you're in the top tier of active players by farming volume.

FAQ

What is the rarest aura in Sol's RNG after Eon 1.20?

Astraios at 1 in 1,750,000,000. It's Challenged+ tier, Singularity Biome exclusive.

What Singularity auras can I roll without the Singularity Biome?

Pleiades (1 in 65,000), Pulsar (1 in 83,345), and Constella (1 in 86,000) are all rollable in normal play. Vega, Centurion, Oculus, Projection, and Astraios require the Singularity Biome.

How much Luck does the Singularity Biome give?

1.1x Total Luck multiplier for the 20-minute window. Stacks multiplicatively with all other active buffs: potions, event bonuses, passives.

How do I craft a Singularity Catalyst?

You need: 1x Gargantua, 2x Sirius, 5x Orion, 5x Galaxy, and 30x Comet. Gargantua (1 in 430M) is the hardest component. All components now drop exclusively in the Singularity Biome, including Gargantua, Galaxy, and Comet, which moved from Starfall in Eon 1.20.

What is Master-Hand in Sol's RNG?

A Craftable/Transcendent-tier aura unlocked by reaching 1,250,000,000 total collected stat milestone. It doesn't roll from probability. It's a deterministic progression reward for sustained farming volume.

How many new auras did the Singularity update add?

13 total. Of those, 9 have been community-verified with confirmed names and odds. The remaining 4 are still unconfirmed, with no verified names or odds.

Did Starfall get removed?

No. Starfall still exists but three auras (Gargantua, Galaxy, Comet) moved from Starfall to Singularity-exclusive in Eon 1.20. Starfall's remaining aura pool is still farmable.

Is the Singularity worth grinding for average players?

The biome itself requires a Catalyst that's gated behind a 1-in-430M component (Gargantua), so crafting from scratch is endgame content. The three rollable Mythics (Pleiades, Pulsar, Constella) from this update are accessible without the biome and are worth targeting at all levels above early-game.
