The moment Nial had adjusted to his strength, he began to experiment with the Forgotten runic constellations he had received from Damian's memories.
First, Nial engraved the easiest runic constellations on an ordinary piece of paper until he reached a high enough perfection grade. Afterward, he compared their complexity with other runic constellations before he tested the potency of the forgotten runic constellations.
Having been forgotten didn't mean that the forgotten runic constellations were better or their potency greater because they were rarely used. That was also why Nial began to do testing with the simplest runic constellations before he compared them to other Basic, Intermediate and Advanced runic constellations.
Interestingly enough, Nial got to know a lot more about the runic constellations, their perks, and the high compatibility some forgotten runic constellations had with other runes.
