Familiar Star Up

All Familiars you’ll get will start with one-star. Star Up is a method of increasing the Familiar’s stars. Not only does this increase the familiar’s stats, this method also improves their skills. So far, this is the only method to increase the familiars’ skills. To increase the familiar’s star, you’ll need to have extra copies of the same familiar. In the same example below, to raise this S-rank familiar to 2-stars, you’ll need two copies and 200,000 gold. Lower-grade familiars will require multiple copies but at a cheaper cost. Don’t hesitate to star up your default familiar (also named Star) since its skills can be helpful in the long run, until you get better familiars to strengthen.
