Normally, most Spirit Beasts awakened only one Ultimate Skill in their entire life, and some lucky ones could awaken a Second Ultimate Skill after breaking through to Rank 7.
So, Ethan knew just how important the Second Ultimate Skill was for Spirit Beasts.
Among his pets, Celea could be excluded since she already possessed the [Celestial Dragon Body].
Yuno, the Heavenly Star Fox, was a Heavenly Beast and naturally had a higher chance of awakening a second Ultimate Skill compared to regular Spirit Beasts.
The same applied to the Blood Dragons—though even if they didn't awaken a second Ultimate Skill, their bloodline and racial traits alone made them far stronger than ordinary Spirit Beasts.
Finally, there were two Spirit Beasts who could directly benefit from the Celestial Dragon Scale to awaken their Second Ultimate Skill: Fang, the Golden-Eyed Silver Wolf, and Pebble, the Mystic Soil Turtle.
