Exort Essence

Btw, you said you already have the esssence, so I was confused.
Edit: My bad, I thought you were the OP.

Greevils have levels and these effect their abilities, their level is based on the amount of essences that were put into the egg. You can have 3 essences of each exort, quas, wex, and unusual. A shadow essence will override all essences in an egg except for unusual because unusual essences do not effect abilities, just visuals. To make a colored Greevil you want just use common color sense. Like 3 quas and 3 exort will create a purple Greevil.

If you need help with figuring out what each type has to offer, Google something along the lines of "Greevil Abilities".

OK, thanks for the info :)+1
