Egg of Prophecy

Eggs of Prophecy (EoP), also unofficially called Prophecy Eggs (PE), are rare mystical Eggs added in Version 1.7. They function as an extra multiplier of your current Soul Eggs, increasing their multiplier by 5% per Egg of Prophecy. They are referred to as 'rare Soul Eggs' in the explanation message. The Epic Research 'Prophecy Bonus' raises the bonus gained by 1% compounding. Since they compound, their multiplier starts growing very quickly once the quantity builds up.

The first time an Egg of Prophecy is obtained, a message explaining them appears:

Obtaining[]

Eggs of Prophecy can be obtained from Contracts, Trophies, and the Daily Gift Calendar. There are a limited supply of Eggs of Prophecy a player can get, dictated by the number of current contracts available. With the introduction of Leggacy contracts, Eggs of Prophecy from all past contracts can be obtained if the player plays long enough. As well, with a subscription to Egg, Inc. Ultra (started Aug 2023), one additional Leggacy contract can be run each week, roughly halving the amount of time required to 'catch up'. Seasonal rewards will also offer EoP, details found in this medium article.

	Contracts	Trophies	Daily Gift Calendar	Seasons	Total Eggs of Prophecy
Maximum number available	163	40	24	1	228**
How often does maximum available increase	Whenever Kevhen decides to.	Never	Never	Once per Season (4 per year)*

*The exact day a Season starts is usually on the first Monday after the relevant solstice or equinox, measured in the Pacific Time Zone.

**The in-game screen showing the total available EoP is often incorrect, or off my one. It is speculated that it needs to be manually updated by the developer each time a new EoP is released.

Compounding[]

Below, you can see the result of various amounts of prophecy eggs combined with the epic research that improves them from 5% to 10% per egg, but you can always calculate the effect of your Prophecy Eggs as a multiplier equal to ((105 + Prophecy Bonus)/100)^Number of Prophecy Eggs.

Trivia[]

If Prophecy Bonus is upgraded before obtaining any Prophecy Eggs, the popup explaining Prophecy Eggs will show the increased bonus instead of the base.
The best and the most consistent way to earn Prophecy Eggs is to join a contract with coops. They are the only method to gain more Prophecy Eggs.
Prophecy Bonus is the most expensive first Epic upgrade, as it costs 100,000, which is equal to both buying the Hyperloop Station and upgrading the Fuel Tank. This means that until your number of Prophecy Eggs is very large, you are usually better off with Soul Food, then Epic Comfy Nests, then Prophecy Bonus, in that order.
With Artifacts, the compounding bonus from Prophecy Eggs can reach up to 12.85% percent!
- With Enlightenment overclocking, the bonus can reach 13.45%!
