Reach the required Skill Level to upgrade Skills; max them out and they will automatically evolve! From [Slacking Off] to [Invisibility], from [Slashing] to [Phantom Sword Dance], from [Fireball Technique] to [Scorching Flame Meteor]... As long as he keeps grinding, he can continuously grow stronger. “So, what's the next commission? Tell me where the Demons are hiding. Without monsters, how am I supposed to farm Skill Level?”
