Evolution

Evolution is a natural growth to some animals and hybrids. Not all the animals will get their evolution, instead those who don't evolve at all just grow by their height and minor appearances.

Description
When an evolvable animal wants to evolve, they will require the required level and the amount of element berries. If enough, they will evolve into a creature which is even powerful than before. They will grow tougher and may get more chances to get better ranks in their jobs.

Age also affect evolution, simply because of their life stage. If their stage is comfortable with their current power, they will evolve as well.
