Every pet is graded from E up to
S. When an egg hatches, each of its three stats,
Health, Attack, and Speed, rolls its own grade
based on the potential sleeping inside the egg. Most rolls land where the egg was destined to be, but a stat can
come out a step weaker… or, rarely, a step or even two steps stronger. Two pets of the same species can hatch
very differently. A lucky roll is worth celebrating.
A stat's grade determines how quickly it grows in training, so a high-grade stat pays off for the pet's whole life.
You can keep up to 10 hatched pets in your stable;
beyond that you'll need to release one to make room. Choose carefully. Releasing is forever.
