Damien was enjoying his stay on the second steps of the mountains.
He learned so many new magic and techniques in his short stay.
He now meditates, it replenishes his mana way faster and smoother. It also helped him to regulate his breathing as the air was lacking compared to any other place.
He knew this was just the beginning as the more he climbed, the less air to breathe, and to adjust to that, meditation was the best. He could control and regulate the amount of air he can take in his lungs and this can also increase his lung capacity.
This is especially helpful in battling monsters and animals, as the lack of oxygen during a fight can lead to fatal injury and, in this case, death.
And the best part was that he's eating mana beasts now. This can increase the amount of mana inside someone's body and it can purify the mana and regular intake of it can increase and change physical aspects as well.
