Hellborn is 1 in 2,644,600,640, and Breakthrough can't give it to you. It only rolls while the Hell or Glitched biome is active, so every hour you spend in a normal biome does nothing for it.

So this is a biome-control problem more than a luck problem. Hell costs more to reach than it looks, and the three ways to force it are further down, with the real cost of each.

Every Eon 1-28 Aura

Eon 1-28 went live on September 19, 2026. At least four new auras went in:

Aura	Tier	Where	Native odds	Breakthrough odds
Hellborn	Challenged+	Hell or Glitched	1 in 2,644,600,640	Not possible
Volcanic	Glorious	Hell	1 in 80,000,000	1 in 480,000,000
Virtual : Ultimate	Exalted	Cyberspace	1 in 40,000,000	1 in 80,000,000
HellFire	Epic	Hell	1 in 796	1 in 4,776

Oblivion and Memory also got reworks on September 19.

Three of the four new auras are Hell auras. Hellborn is the one everyone's talking about.

Hellborn

Rolling it pops a server-wide message: [Username] has become Hell's so-called God. The Stat Tracker credits Mincraft_f2p with the first one.

Next to the rest of Hell's pool, Hellborn is about 33 times rarer than Volcanic and about 187 times rarer than Hellbound, which was already the Hell chase aura before this update.

Volcanic

At 1 in 80 million in Hell it sits between Bloodlust (50 million) and Pythios (111 million). Unlike Hellborn, Volcanic can also come from Breakthrough outside Hell, at 1 in 480 million. Don't bother.

Virtual : Ultimate

This is the odd one out: a Cyberspace aura, not a Hell one. It's the fourth mutation of Virtual, which gives Virtual more non-limited mutations than any other aura. The wiki notes it was first pitched as a replacement for Virtual : Full Control, but it shipped as its own aura.

HellFire

The one you'll actually see. At 1 in 796 inside Hell it's the most common aura in the pool now, ahead of Undead at 1 in 2,000. Nobody is chasing it, but it tells you you're rolling in the right place.

The Hell Aura Pool

Hell has a 6x Breakthrough multiplier. Every native aura below is six times easier inside Hell than outside it, except Hellborn, which has no outside odds at all.

Aura	Odds in Hell	Odds via Breakthrough
HellFire (new)	1 in 796	1 in 4,776
Undead	1 in 2,000	1 in 12,000
Undead : Devil	1 in 111,111	1 in 666,666
Hades	1 in 1,111,111	1 in 6,666,666
Hellbound	1 in 14,166,666	1 in 85,000,000
Felled	1 in 30,000,000	1 in 180,000,000
Bloodlust	1 in 50,000,000	1 in 300,000,000
Volcanic (new)	1 in 80,000,000	1 in 480,000,000
Pythios	1 in 111,111,111	1 in 666,666,666
Hellborn (new)	1 in 2,644,600,640	Not possible

Left alone, Hell has a 1 in 6,666 chance per second to spawn and lasts 666 seconds (11 minutes 6 seconds). Waiting for it is a bad use of a session, so force it.

Farm Hades while you're in Hell: you need one to craft the Biome Randomizer, and Hell is where it's six times cheaper.

How to Force the Hell Biome

Strange Controller, Biome Randomizer, Biome Selector. They aren't close in value for a Hellborn hunt.

Item	Hell chance per use	Your cooldown	Server cooldown	Average time per forced Hell
Strange Controller	2.49%	20 min	20 min	About 13.4 hours
Biome Randomizer	11.087%	35 min	20 min	About 5.3 hours
Biome Selector + Infernal Flame Drive	Guaranteed	1 hour	20 min	1 hour, plus 5 Eternal Flames

The last column is just the odds times the cooldown. A 2.49% chance works out to about 40 uses on average, and 40 uses at 20 minutes each is roughly 13.4 hours.

Strange Controller

It respects each biome's natural spawn rate, which is why Hell comes up only 2.49% of the time. Windy (33.18%) and Snowy (27.65%) eat most of your uses.

The recipe at Jake's Workshop is one each of NULL?, Eternal Flame, Piece of Star, Curruptaine, Rainy Bottle, Icicle, Wind Essence and Feather Vial. The Eternal Flame in that list comes from Hell, so you have to reach Hell once just to build the thing that sends you to Hell. And then it only lands on Hell 2.49% of the time.

Weak.

Biome Randomizer

It ignores natural spawn rates, so Hell comes up about once every nine uses. The price is the recipe: four Strange Controllers plus Undefined, Hades, Poseidon, Galaxy, Astral, Permafrost, Stormal and Divinus : Guardian.

Already own one? Big step up from the Controller. Collecting those eight auras from scratch is its own grind.

Biome Selector (the real answer)

Pick Hell, spend a Drive, and get Hell. You unlock the recipe with the Access Granted achievement, which you earn by triggering Cyberspace. The recipe is one Biome Randomizer plus one Cyber Technology.

The Drive for Hell is the Infernal Flame Drive, and it costs 5 Eternal Flames. The Selector uses up the Drive each time.

The catch: Eternal Flames only spawn at item spawn points when a Hell biome starts, and they despawn after about two minutes. The wiki doesn't say whether a Selector-forced Hell drops Flames the way a natural one does. Until it does, don't count on Hell paying for its own Drives.

Pick up every Flame you see in a natural Hell. Every five you bank is one guaranteed Hell later.

The server cooldown trap

All three items share a 20-minute server cooldown. If someone else in your server just used one, yours won't fire. In a busy public server, other players' cooldowns will block you more than your own 1-hour Selector timer. A private server avoids the queue.

The Glitched Backdoor

Hellborn's page lists Glitched as its other biome. Glitched is the rarest biome in the game: 1 in 30,000 per biome change, and it lasts only 164 seconds.

In Glitched, native auras from normal biomes ignore Breakthrough odds and roll at their native rarity. That's how a Hell aura can drop without Hell.

You can't plan around it. The Biome Randomizer can't force Glitched either; its page says Glitched only shows up at its natural 1-in-30,000 rate.

New Code: UPD20260919

Eon 1-28 came with the usual update code. All three of these still work, per the wiki's Codes page:

Code	Reward
UPD20260919	20 Potion Chests, 5 Rare Potion Chests
UPD20260905	20 Potion Chests, 5 Rare Potion Chests
SRY4DEALY	20 Potion Chests, 5 Rare Potion Chests, 3 Hwachae

SRY4DEALY really is spelled that way. An earlier update code, UPD20260228, expired two weeks after the date in its name, so don't sit on UPD20260905. Our Sol's RNG codes page tracks expiry.
