Bird

Overview
An easily acquired Air Mount, it's as mediocre as it is common. A complete lack of skills and abilities, as well as average Stats and Stat Growths gives them little value as combat units. They have no value at your Farm either as they don't produce anything.

Breeding
As one of the few units in-game that have no skills whatsoever, they make a good template for messing around, especially with the additional options that some Essences give. If you think you've learned all there is to learn about how the Farm works, try making yourself a custom Bird. For example, make a "thunderbird" using both breeding and fusing. It should have Magic or Dexterity Level Type, at least one electrical spell, and it should be bigger than its parents.
