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.
