Behind a waterfall in the Angels and Demons biome lies Steal an Egg’s most coveted Secret Fusion Shrine, where the rarest pets combine into extraordinary eggs.
Accessing the Shrine Requires Speed and Rarity
Players must have earned at least 20 billion Speed to reach the biome. Only Light and Dark pets of Eternal or Divine rarity accepted. Pets from prior biomes cannot be used.
Where to Locate the Hidden Entrance
Stand near the biome’s final gate, then locate the waterfall directly opposite. The stream—blue on the Angels side, lava on Demons—serves as the portal. Walk forward and, if blocked, keep moving and jumping to slice through the water.
Fusion Pedestals Explained
Inside the shrine, a yellow pedestal hosts Light pets; a red pedestal holds Dark pets. Place one eligible pet on each, then watch the animated fusion complete. No permanent trading is required; two players can each receive an egg.
Fusion Recipes and Results
- Pegasus (Light) + Skeleton Horse (Dark) → Equinox egg
- ArchAngel (Light) + World Burner (Dark) → Aetheron egg
Store the egg in a pen to hatch. Aetheron, for example, yields roughly 6.9 billion per second, potentially higher if mutations apply.
When to Farm for Optimal Success
The Angels & Demons biome cycles through versions. The merged version provides both Light and Dark pets simultaneously, plus a luck bonus that raises the chance of rare finds. Stockpile Pegasus, Skeleton Horse, ArchAngel, and World Burner during this window before attempting repeated fusions.
Now the shrine is open for late‑game players to mix Divine and Eternal pets, turning their collection into potent, high‑earning eggs.
