Magic Might and Maturity

Is a magical animal born with its full Magic Might score, or does it increase during the animal's youth, reaching its maximum value when the animal reaches its maturity? Realms of Power: Magic does not answer this question, but does state that it takes many magical animals five years to reach full maturity, at which point they should have all their required Ability scores. The griffins described in Legends of Hermes do gain in Might as they grow in years; a mature male has a Magic Might of 30, while a hatchling has a Magic Might of 5. We suggest that other magical animals follow suit.

A rough rule of thumb to determine its Might during its early years is to divide the adult creature's Magic Might by 5. If a creature matures sooner, say after 3 years, divide its adult Might by 3 to determine its Might at birth and in its juvenile stage. Your storyguide is the final arbiter. A magus interested in taming a magical animal will find it easier to train a youngling than an adult specimen, which makes a certain amount of sense.
