A Soul Egg

Soul Eggs are a common type of Mystical Egg primarily gained from Prestige that grant a persistent permanent 10% boost to all future earnings, which can be raised further with Soul Food and Eggs of Prophecy.

They resemble stones with a purple icosahedral jewel set inside.


You gain Soul Eggs by prestiging, completing certain Challenges or Trophies, the Daily Gift Calendar, or sometimes goals in a Contract.

The information below implies that Soul Beacons do not work, but Soul Beacons appear to work, implying that the information below is inaccurate.

The Soul Eggs you earn when prestiging are calculated based off of your total prestige earnings, via the following formula.

Your prestige earnings can be found under Stats.


There are a few ways to increase the power of Soul Eggs.

Soul Food

Soul Food, an Epic Upgrade, strengthens the ability of Soul Eggs. Each level adds a 1% boost to all Soul Eggs (e.g. a level 14 would have a 14% boost). Soul Food has 140 levels, with a maximum of 140% bonus to egg value per Soul Egg.

Eggs of Prophecy

You can increase the potency of soul eggs by 5% (compounding) with Eggs of Prophecy. Each Prophecy Egg increases the potency of all soul eggs by 5-10%, depending on your level of Prophecy Bonus, an Epic Upgrade.


  • An icosahedron is a 3D shape with 20 polygonal faces. The jewel inside the Soul Egg is a regular icosahedron, which means its 20 faces are all equilateral triangles, and this means there are 5 faces visible around each vertex, leading to the 5 most visible faces of the jewel in this picture.
