Halloween Event Guide - Sol's RNG Wiki
The largest recurring seasonal event in Sol's RNG, spanning 2024 and 2025: currencies, the GRAVEYARD and BLOOD RAIN biomes, 41 limited auras, event-tier rarities and seasonal gear.
Overview
Halloween is the biggest recurring seasonal event in Sol's RNG, delivering the largest aura drops of any event across 2024 and 2025. It spans two editions with distinct currencies, the spooky GRAVEYARD and PUMPKIN MOON biomes, and the summonable BLOOD RAIN that introduced the first event-tier auras above one-in-a-billion rarity.
Halloween Event Comparison
The 2024 debut and the 2025 expansion reshaped the event dramatically. The first run leaned on Pump Tokens and ten new auras, while 2025 doubled down with Bounty Medals, 31 new auras and the first EVENT-tier drops ever, making it the largest aura event in the game's history.
| Edition | Dates | Currency | New Auras |
|---|---|---|---|
| Halloween 2024 | Dec 1, 2024 – Feb 8, 2025 | Pump Tokens | 10 |
| Halloween 2025 | Oct 18 – Nov 30, 2025 | Bounty Medals | 31 |
How to Summon BLOOD RAIN
BLOOD RAIN is the standout 2025 biome, summoned only through the Cursed Rune Fragment item while a GRAVEYARD or PUMPKIN MOON biome is active. It is the first biome to host two TRANSCENDENT exclusives, so coordinate your summon windows with high-luck potions and rolls before the timer runs out.
Roll a night-only biome
Wait for or force a GRAVEYARD or PUMPKIN MOON biome, since both only spawn at night and do not allow breakthrough auras from outside.
Use the Cursed Rune Fragment
Activate the Cursed Rune Fragment during that biome to summon BLOOD RAIN, which overlays its own exclusive TRANSCENDENT auras on top of the night biome pool.
Roll with max luck
Stack your strongest luck gear and potions for the duration, as BLOOD RAIN windows are short and the two TRANSCENDENT exclusives are extremely rare.
Bounty-Token Auras & Gear
The 2025 Bounty Medal shop offers a ladder of purchasable auras, climbing in price and prestige from Veinweaver up to THANEBORNE. Seasonal gear like the Ominous Coffin and Vampire Hunter also unlocks here, giving permanent stat boosts that carry beyond the event.
Veinweaver (4k)
The entry-level Bounty Medal aura at four thousand medals, a budget-friendly pickup for active bounty hunters.
DREADSEA (6k)
A mid-tier six-thousand-medal aura with a striking oceanic horror visual and a solid rarity benchmark.
CAROUSEL (8k)
An eight-thousand-medal showcase aura that pairs cinematic flair with a notable collection boost.
LAMENT & THANEBORNE
The prestige caps of the shop at 22k and 25k medals, gating the most coveted bounty-tier auras.
Halloween 2024 Highlights
The original Halloween 2024 run introduced Pump Tokens as currency, spendable at Jack The Pumpkin for seasonal stock. It added ten new auras including PUMP, Lunar Nightfall, Vital, HARVESTER and APOSTOLOS: VEIL, alongside the GRAVEYARD and PUMPKIN MOON biomes and the iconic Pump Punch gear that became a permanent staple of the event.
Seasonal Items, Gear & Currency Shift
Halloween evolved sharply between editions, with currency shifting from Pump Tokens to Bounty Medals in 2025. The gear pool grew alongside it, and the event introduced the first items capable of summoning a custom biome, setting the template that later seasons like Summer would follow.
- 2024 currency: Pump Tokens, where one token equals one Pumpkin, spent at the merchant Jack The Pumpkin.
- 2025 currency: Bounty Medals replaced Pump Tokens and gated the largest aura shop in any event.
- Key items: Pumpkin, Pump King's Head, Cursed Rune Fragment and Blood Pack across both editions.
- Seasonal gear: Pump Punch (2024) plus Ominous Coffin and Vampire Hunter (2025).
- Season Pass III (2025): Slaughter was the Tier 50 capstone aura for the Halloween track.
