Leviathan Egg at a glance
Leviathan Egg is a recorded egg from the Lake area, with Cosmic as the highest recorded rarity in its contents. Its recorded result is Leviathan, a Cosmic pet.
Pooled eggs are the part of this game that is easiest to misread. A single egg artwork can hide several pets with very different rarities, which is why this page lists the whole pool instead of a single headline value.
Leviathan Egg quick facts
Where to find Leviathan Egg
Leviathan Egg belongs to the Lake area. Reach that area with a route you can complete consistently, steal the egg, and return it to your base before hatching. If the Lake route is still marginal at your current Speed, run a nearer area first and come back once the return leg is comfortable.
The return leg is what decides most attempts. Measure your own round trip, then add a buffer for a slower server. The egg itself does not change, but your chance of keeping it does.
Leviathan Egg rarity
The highest recorded rarity in Leviathan Egg is Cosmic. That is a label from the record, not a probability. It tells you how far into progression this egg belongs, not how many attempts a specific result will take.
If you are comparing two eggs, read the whole pool rather than the top rarity alone. An egg with one high-rarity entry and five weaker entries behaves very differently from an egg that is consistently strong across its pool.
