In Steal An Egg, World Burner is the top pet on the Dark side. It has Divine rarity, comes from the Darkness version of the Angels & Demons biome, and earns $5 billion each second by itself. To get one, you’ll need to meet a demanding Speed requirement, arrive during the correct night, and bring the egg back safely.
Quick answer: Build your Speed to 20 billion for access to the Angels & Demons biome. When the Demons (Dark) night is underway, take the demonic egg from its nest, get it to your SAFE ZONE pen, and hatch it.
World Burner stats and unlock requirements
World Burner is the Dark counterpart to ArchAngel; the two pets debuted in the Angels & Demons update. Their income and Speed bonuses match, placing World Burner among the top two pets available through direct hatching. The stolen egg appears in your inventory’s Eggs tab under the name Kingdom & Demonic Egg.
| Attribute | Value |
|---|---|
| Rarity | Divine |
| Biome | Angels & Demons (Dark) |
| Money per second | $5B/s |
| Speed bonus | +600 million |
| Biome unlock | 20 billion Speed |
| Income unlock cost | ~$500B in-game cash |
| Grow time | 15h+ |
A very high Speed stat is the key to entering this biome. You can’t purchase the pet or obtain it from a code. Before trying, tune your treadmill setup and Speed multipliers to reach the zone during the brief window available each cycle.
- 20 billion Speed is the requirement for access to the Angels & Demons biome.
- The rotating zone must be in its Demons (Dark) night phase; it isn’t available outside that window.
- Keep about $500B in the bank to unlock the pet’s full income tier.
When the World Burner egg appears
The biome switches nightly between Angels (Light) and Demons (Darkness), with a distinct guardian and egg selection for each state. You need the Demons night to find the Dark eggs. A less frequent Merged night opens both egg pools and adds a luck boost, making it the best opportunity to roll either Divine.
Map eggs refresh every 5 minutes: collection runs for roughly 4 minutes 50 seconds, then night lasts 10 seconds. Eggs grow 30 times as quickly during this brief night phase. Divine eggs are randomly selected at resets, and the server announces each one along with its location; look for a notification identifying a Divine egg in Angels & Demons.
How to steal the World Burner egg
Keep the Drop button untouched as you run. If you release the egg, anyone can take it before you have a chance to retrieve it.
Confirm the steal and hatch the pet
When you enter your pen, the screen displays You stole an EGG! This confirms the egg has been placed in your personal yard and recorded in the Eggs inventory tab. It rests on a pedestal while its grow timer counts down, taking roughly 18 hours from fresh.
At the end of the countdown, the pedestal displays Egg Ready! and offers an E Hatch! prompt. Interact to hatch the egg into World Burner, a large demon with wings and horns that lands in your fenced plot. The pet is also added to your Pet Index, confirming the Divine is unlocked. To skip the wait, use Instant Grow All and complete the timer immediately.
Boost World Burner income with mutations
Apply mutations before hatching, while the egg remains on its pedestal; any mutations stacked on it transfer to the pet. Equip a mutation item, then click the egg and look for a success notice such as Scrambled mutation applied! or Fractured mutation applied! An attempt may fail with text like “The mutation failed” or “The consumable fizzled…”, so repeat the process until a mutation succeeds.
Get Scrambled mutations from Dr. Scramble experiment samples, which you farm by defeating Dr. Scramble experiment mobs; Fractured mutations require shards. Speed boosts are also available in the Dr Scramble’s Experiments shop and can help you reach the biome sooner on future runs.
The reward is substantial: World Burner’s standard rate is $5B/s, while the Fractured version earns more than four times as much.
| Version | Income |
|---|---|
| World Burner (base) | $5B/s |
| Fractured World Burner | $21B/s |
Do all mutation work before hatching. Once the pet is out of the egg, you cannot go back and add a mutation to that pedestal roll.
Fuse World Burner into Aetheron
If you have World Burner and ArchAngel, merge them at the Fusion Shrine. Place ArchAngel on the Angel pedestal first, then put World Burner on the Demon pedestal. The Shrine produces a Fusion Egg; hatch it to get Aetheron, a Divine the community regards as the game’s strongest pet.
Only the new top-tier pets from Angels & Demons can be fused; older Divine pets, including the Unicorn, are ineligible. Save the Shrine for endgame, once you have both apex Divines—it won’t help you acquire World Burner in the first place.
No codes for the World Burner
Steal An Egg has no active codes or in-game redemption box. Getting World Burner requires Speed farming and egg hatching, so claims that a code grants the pet are fabricated. Raise your Speed, wait for Demons night, and take the egg yourself.
