What is the latest Sol's RNG update?
The newest Sol's RNG update documented on the Sol's RNG Wiki (read on outubro 24, 2026) is Eon 1-30, which the aura pages call the Radiant Forest Update. Their changelogs date it outubro 17, 2026. It adds the Lost Forest biome, a rare biome called The Radiant Forest that you summon with a crafted item, and a chain of "True" auras that ends in Tomorrow, a Challenged+ aura.
One caveat before the details. The wiki's main changelog, atualizações/Eons, stops at Eon 1-26.5 (agosto 15, 2026) and carries a stub notice that the Hellborn update is missing. So this guia is assembled from the pages that did get updated: Biomes, the item pages and about two dozen aura pages. If you saw a balance change or a código in-game that isn't here, that's why. For códigos, check the Sol's RNG codes page, and for older patches the atualização log.
Lost Forest: the new regular biome
The Biomes page lists Lost Forest as "released in the Eon 1-30 atualização" and gives it these estatísticas:
- Spawn chance: 1 in 8,128 per second
- Duration: 450 seconds (7 minutes 30 seconds)
- Breakthrough multiplier: 2x
- 17 native auras, five of them mutações
That brings the total to 11 regular biomes, 5 rare biomes and 7 evento biomes, according to the same page.
What does 1 in 8,128 per second mean in practice? The average wait is 8,128 seconds, a little over 2 hours 15 minutes of server time. The chance of at least one Lost Forest in an hour is 1 − (1 − 1/8,128)^3,600 ≈ 36%, and in three hours about 74%. Don't sit in one server waiting for it.
Here's the part most patch summaries skip: most of the Lost Forest pool is not new. The aura changelogs show that Flora, Flutter, Flutter : Buggify, Lantern, Marsh, Flora : Florest, Runic, Runic : Wilt, Lily, Perpetual, Flora : Evergreen, Ruins and Ruins : Withered all had their native biome "changed to Lost Forest" on outubro 17, 2026. Auras you already chased elsewhere now have a 2x native rate here.

Counting the rows: 13 of the 17 were moved from other biomes and 4 are brand new. Tree House is the headline: a Transcendent with five abilities, covered in the Sol's RNG auras with abilities guia.
The Radiant Forest: how to summon it
The Radiant Forest doesn't spawn on its own. The Biomes page says it appears only when you use a Condensed Memory inside Lost Forest during Nighttime. Both conditions at once, so you need a Lost Forest that overlaps with night.
The Condensed Memory page lists the recipe, crafted at Jake's Workshop:
| Ingredient | Quantity | Rarity (base / best native) |
|---|---|---|
| Scattered Condensed Memory | 1 | From Stella's 3rd quest, or returned after using a Condensed Memory |
| Kyawthuite | 70 | 1 in 850,000 / 1 in 425,000 in The Radiant Forest |
| Twilight | 70 | 1 in 6,000,000 / 1 in 600,000 at Nighttime |
| Jade | 150 | 1 in 125,000 / 1 in 62,500 in The Radiant Forest |
The Scattered Condensed Memory note says you can hold only one at a time.
How long does the first one take? Each roll can only give one aura, but over a long session you collect all three at once, and the expected count of any aura after k rolls is k × luck / N. So the slowest ingredient decides it. At 1x luck and outside The Radiant Forest:
- 70 Kyawthuite ≈ 70 × 850,000 = 59.5 million rolls
- 70 Twilight at night ≈ 70 × 600,000 = 42 million night rolls (or 420 million at day rates)
- 150 Jade ≈ 150 × 125,000 = 18.75 million rolls
Divide by your luck. At 10x it's about 5.95 million rolls for the Kyawthuite. Kyawthuite is the bottleneck, and Twilight is the trap: roll it during the day and you're ten times slower. Plug your own luck into the Sol's RNG calculator.
Once you're inside, the native rates for Jade and Kyawthuite are twice as good (9.375 million and 29.75 million rolls for the next batch at 1x), which makes the second Condensed Memory cheaper than the first.
Inside The Radiant Forest
Per the Biomes page, the biome lasts 900 seconds (15 minutes), locks the time to Nighttime and has a 2x breakthrough multiplier. It also adds Moon Catch: stars fall from the sky inside marked circles, and each one you catch gives a stack of Cor Lunae's Blessing, worth +0.015x final luck, up to 10 stacks (+0.15x total).
Its roll pool:
| Aura | Chance in The Radiant Forest | Breakthrough? |
|---|---|---|
| Watcher (Epic) | 1 in 5,000 | No |
| Rekindle (Epic) | 1 in 7,500 | No |
| Jade | 1 in 62,500 | Yes, 1 in 125,000 |
| Kyawthuite | 1 in 425,000 | Yes, 1 in 850,000 |
| Jade : Purity | 1 in 4,625,000 | Yes, 1 in 9,250,000 |
| Moonchild (Mythic) | 1 in 5,000,000 | No |
| Cor Lunae (Exalted) | 1 in 50,000,000 | No |
| Kyawthuite : Remembrance | 1 in 225,000,000 | Yes, 1 in 450,000,000 |
Watcher, Rekindle, Moonchild and Cor Lunae are new and can't be rolled anywhere else.
The Seven Radiant Moons and Tomorrow
This is the system the whole atualização is built around. A row of seven moons sits at the top of the screen in The Radiant Forest, and each lights up when you roll a specific aura. The Biomes page groups them:
- 1Jade + Jade : Purity grant the True Jade buff, which lets you roll True Jade at 1 in 10,250,000.
- 2Kyawthuite + Kyawthuite : Remembrance grant True Kyawthuite, rollable at 1 in 825,000.
- 3Twilight : Withering Grace + Twilight : Iridescent Memory + Twilight grant True Twilight, rollable at 1 in 6,000,000.
- 4All seven moons grant "The 8128th Cycle," which guarantees your next roll is Tomorrow.
Look at the third group. Twilight : Withering Grace is 1 in 42,265,600 at night and Kyawthuite : Remembrance is 1 in 225,000,000 even at its native rate. Getting all seven is a long-term project. The Tomorrow page says the seven auras can be rolled in any order but all within a single Radiant Forest biome, so plan to finish the set before the 15 minutes run out.
And the number 8,128 isn't random. It's Lost Forest's spawn rate, the name of the buff, and the counter in Tomorrow's cutscene, which the wiki says plays clips of Mythic-to-Glorious auras while a number climbs from 0 to 8,128.
Smaller changes around Eon 1-30
These come from pages that reference Eon 1-27 through 1-30:
- Hellborn (Eon 1-28): Challenged+, rollable only in Hell or Glitched at 1 in 2,644,600,640.
- Content Deleted (Eon 1-29): added back in Eon 1-17, made obtainable in Eon 1-29 inside Glitched at 1 in 4,040.
- Summer 2026 is over. The eventos page dates it agosto 1 to outubro 3, 2026. Season Pass Season VIII ended setembro 25, 2026.
The wiki lists no new gears or potions for Eon 1-30, so the gears and potions pages are unchanged by this atualização. For the evento calendar, including whether a Halloween event has shown up yet, see the Sol's RNG events guia.
What to do first
If you're returning after Summer 2026, the order is simple. Roll at night whenever you can, because Twilight is the ingredient that punishes day rolling. Do Stella's quests until you have the Scattered Condensed Memory. Keep an eye on chat for Lost Forest, since the server announces every biome except Normal and Glitched, and save a Condensed Memory until a Lost Forest lines up with night. Everything else is the biome list and patience.
