Greevil Egg

''It is said (by some elder sage or other) that the hatchlings are highly susceptible, and that each essence exerts a unique influence on the incubating creature. Is there method to this madness? Trial and error, and some comparison of results, will surely reveal the rules of Greevil husbandry.''

Greevil Eggs could be bought from the store, traded for, dropped in-game, or found in a chest. Each egg could be imbued with one of several Essences, which could be traded for or acquired during Diretide 2012, Frostivus 2012, and Diretide 2013. A single Greevil Egg was given out to those who defeated Roshan during Diretide 2012.

Every Greevil Egg could be slotted with up to nine Essences (up to three each of Quas, Wex, and Exort Essences), or a single Shadow Essence. Different Essence combinations produced different egg names and colors, and when the player decided to hatch it sometime after Diretide 2012, they would receive a Greevil courier in one of nine colors and with different physical properties, depending on the Essence combination used. Additionally, each egg could be imbued with up to three Unusual Essences, with each increasing the intensity of the particle effect corresponding with the color of the hatched Greevil courier.
