Unfortunately, being a True Celestial was not easy.
He had to possess the knowledge to manipulate things before he can learn to transform or change his body.
It means that during that time, being a craftsman was the best option. Not only will it give him enough experience, but he would also have more opportunities in gathering resources for his true goal.
He has a difficult goal so he needs to be patient.
And although he was a renowned Magic Craftsman now, his aim had never changed.
Luckily, he was given an opportunity to experience a part of the True Celestial's ability that allows him to extend his sense. It was his Divine Sense…
Although the Pathfinder wasn't just giving it to him, he could understand that it needed to be a form of reward… After all, he later learned that this technology itself was made by the Royal Mayans to mold their young ones.
