Sol’s RNG Halloween biomes are Graveyard, Pumpkin Moon and Blood Rain. All three give you a different pool of seasonal auras to roll, but they do not appear the same way. Two are associated with nightfall, while Blood Rain needs a special item to start.
Each biome has its own exclusive aura pool. That means a Pumpkin Moon aura cannot be treated as a normal Graveyard roll, even though both environments can appear at night. Blood Rain has a separate activation item and a much shorter window.
All three Sol’s RNG Halloween biomes explained
The three Sol’s RNG Halloween biomes are part of the 2026 event running from 31 October to 14 November. Graveyard and Pumpkin Moon appear in the nighttime biome cycle. Blood Rain is the exception: players activate it with a Cursed Rune Fragment bought from Jack the Pumpkin.
| Biome | How to activate | Rolling window |
|---|---|---|
| Graveyard | Nighttime biome appearance | During the active night |
| Pumpkin Moon | Nighttime biome appearance | During the active night |
| Blood Rain | Use Cursed Rune Fragment | 10 minutes after activation |
A 31 October gameplay walkthrough reported a one-in-five chance of either nighttime biome appearing when the night begins. These are reported biome spawn chances, not the odds of rolling a particular aura. The aura probabilities are separate.
Graveyard biome and its Halloween auras
Graveyard is one of the naturally appearing Sol’s RNG Halloween biomes. Wait for nighttime and watch for the biome to become active. When it does, you can roll for the event auras associated with Graveyard for as long as that nighttime environment lasts.
The launch-day event aura list places Ghost, Harvester: Necromancy, Withered and Gaze in Graveyard. These are not purchases from Jack’s shop. Getting them means rolling in the corresponding biome while it is active, and rare results can take a long time even when you have found the correct environment.
Graveyard does not use the Blood Rain fragment. If another biome appears at nightfall, you will need a later Graveyard appearance for its exclusive rolls.
Pumpkin Moon biome and its Halloween auras
Pumpkin Moon is the second nighttime environment. Its event pool is different from Graveyard’s, so work out which aura you want before deciding where to spend your rolling time. Sol’s RNG Halloween biomes reward being in the right environment as well as making the roll itself.
The Pumpkin Moon list recorded on October 31 includes Flushed: Pumpkinity, Enchanted, Lost Soul: Styx, Embercrypt and Cauldron. Those five names appear against Pumpkin Moon rather than the shop-only section of the event collection.
Pumpkin Moon lasts for its active night. Get your rolling equipment ready beforehand so you can use the available window rather than spend it changing gear.
How to start Blood Rain in Sol’s RNG Halloween biomes
Blood Rain is the unusual one. You cannot simply wait for it to appear as another natural nightfall outcome. Instead, buy a Cursed Rune Fragment from Jack the Pumpkin and use the item to activate Blood Rain. Jack appears at night near the hill above Jake’s Shop, beside the pumpkin cart and quest board.
The fragment was listed at 1,600 Hollow Points in the launch-day shop. Once used, the Blood Rain window lasts 600 seconds, or 10 minutes. That short period makes preparation particularly important. Have your equipment and chosen consumables ready before you trigger the biome.
The three auras listed for Blood Rain are Former Garden, Hanahaki and Rejoice. If one of those is your goal, a Graveyard or Pumpkin Moon night is not a substitute. You need the rune-triggered Blood Rain environment and enough rolling time during its active window.
How to make the most of Sol’s RNG Halloween biomes
Start by choosing an aura from one of the three biome groups. For Graveyard and Pumpkin Moon, plan around nightfall and take advantage when the right biome appears. For Blood Rain, earn Hollow Points, buy the fragment and prepare before you use it.
Cruor, Cataclysmic, Acropolis and Deathkeeper are sold by Jack for Hollow Points. None is one of the twelve event biome rolls, so farming the correct currency matters more for those four than waiting for a particular sky.
The Halloween event is scheduled to finish at 8am GMT on Saturday 14 November 2026. If Sol’s RNG Halloween biomes are your route to the seasonal collection, work through the environments before that deadline. For regular redeemable rewards outside the biome system, see our Sol’s RNG codes guide.
The reported biome spawn chances, Blood Rain duration and aura groupings are based on gameplay reporting from 31 October 2026. Sol’s Studio has not officially verified these exact details in a public breakdown.
