Nial was still exhausted when he left the Forest of Life but it was not like that was enough to stop him from returning to Liondra.
He had spent an entire month learning more about Runiciers, what made them special, how to improve the accuracy of one's stroke while engraving runic constellations, and much more.
Nial got to know several new Basic runic constellations and his perfection grade with all of them had reached an exceptional degree. Most runic constellations Nial knew were now at 100% perfection even without the use of the mana-dense runic solution.
Using the mana dense runic solution to reach a perfection grade above 100% was possible but it was much harder to cross the threshold of 100%. After all, the Basic runic constellations were already said to have been improved and researched to the limit.
