The boss of the second floor (4)
There were many changes that occurred because of his breakthrough. Like getting two skill points and three stat points all at once, similar to when he first became a Vigor knight.
His vigor had not only increased in quantity, it had completely transformed into a much more advanced form. Although he didn't test it yet, he could simply tell.
Two of his passive skills increased by a level, [Vitality] and [Veteran's hunch]. And he finally got his first active skill!
As if that was not enough he could actually use EXP to level up active skills. This meant that skill points were better off spent on passive skills.
Esdras didn't immediately get in to fight the boss despite the urge that almost overwhelmed him. He held back because his body had become almost foreign to him.
This was too great of a change that happened in too short of a time.
So, he forced himself to get some exercise. It was only now that he knew how lucky he was to escape from the scavenger.
