The More I Practice, the Less Proficiency I Have in My Skills.

Roger traveled through the fantasy world and became a wild wizard without guidance. While other people's skill proficiency increased steadily by +1 and +1, his skill proficiency dropped wildly by -1 and -1, and his proficiency reached a negative number. Unexpectedly, the lower the proficiency level, the more powerful the spell will be, and it can also undergo advanced transformation! From [Fireball] to [Blazing Fireball], to [Hellfire Meteor]. From [Wind Blade Technique] to [Destroying Storm], and then to [Splitting Air Wind Cut]. Others laughed at him for practicing his skills blindly and making many mistakes. Roger frowned and retorted: I didn't practice blindly, the whole world was wrong!
