New Angels & Demons Biome
Every in-game night, the new biome has a chance to transform into either the Angels version or the Demons version. The active transformation determines which group of animals can appear, so you may need to return across multiple nights to discover animals from both sides.
Each side introduces eight animals, for a total of 16 new animals in Steal an Egg Update #4.
Darkness Animals
| Animal | Rarity |
|---|---|
| Flame Sprite | Legendary |
| Toro | Mythic |
| Imp | Cosmic |
| Demon Hound | Cosmic |
| Gargoyle | Secret |
| RazorFang | Secret |
| Skeleton Horse | Eternal |
| World Burner | Divine |
The Darkness collection ranges from Legendary to Divine. World Burner is the highest-rarity Darkness animal announced for this update, while Gargoyle and RazorFang occupy the Secret tier.
Light Animals
| Animal | Rarity |
|---|---|
| Light Dove | Legendary |
| Winged Lamb | Mythic |
| Sacred Moth | Cosmic |
| Holy Peacock | Cosmic |
| Pure Jellyfish | Secret |
| Centaur | Secret |
| Pegasus | Eternal |
| ArchAngel | Divine |
The Light collection follows the same rarity progression. ArchAngel is the announced Divine animal, Pegasus is Eternal, and Pure Jellyfish and Centaur are Secret animals.
Secret Merged Biome
In addition to the normal Light and Darkness transformations, there is a chance for a Secret Merged Biome to appear. This rare state combines the Angels and Demons themes and grants extra luck while it remains active.
The official announcement does not specify its exact appearance chance, duration, or luck multiplier. Check the live biome and in-game interface instead of relying on an assumed timer or percentage.
Secret Shrine
A Secret Shrine is hidden somewhere inside the new biome. The announcement hints that it holds a secret connected to the Demons, but its precise location, requirements, and rewards were not disclosed.
Explore the entire biome during its different transformations and watch for unusual structures or interaction prompts. Details may become clearer as players discover the shrine in-game.
New Luminous Egg
The Luminous Egg replaces the previous Monster Egg. Like the Monster Egg, it has a rare chance to reroll and unlock a special variant animal—this time, a luminous variant.
This makes the Luminous Egg one of the main collection features in the Angels vs Demons update. The official announcement does not provide exact reroll odds, prices, or a complete reward pool, so confirm those values on the current in-game egg interface.
New Treadmill and Trail Tier
Update #4 adds another tier for both the Treadmill and Trail. These upgrades let players increase Speed beyond the previous progression limit.
Upgrade costs and Speed multipliers were not included in the announcement. You can use the Steal an Egg Speed Calculator once the new in-game values are known.
Bigger Base and One More Pet
A new Base upgrade is also available. Purchasing it expands your progression and lets you equip one additional pet, increasing the number of active income-producing pets you can use.
Use the Steal an Egg Money Calculator to estimate how long an upgrade will take based on your current money and total pet income.
