The next day, as soon as Atticus woke up at 5 AM, he wore his fitted training suit. And without alerting anyone in the camp, he left and headed to the caves to train.
Atticus's training became completely routine, exactly the way he liked it— being persistent and continuously improving.
He 'sparred,' which was basically a total beat down, against the shadow Seraphon, utilizing his elements and arts at full power while also making sure not to kill the poor beast.
After a few hours of this, Atticus found one random wall and sat down, quickly engraving his first 6 runes before drinking the will renewal potion.
Then he sat down cross legged, meditating while also absorbing mana into his mana core.
After fully recovering his will, Atticus engraved the last six runes he had to engrave for the day and then sat, absorbing mana for a few hours.
