These skills that are all marked Ultra Super Rare or whatever are stupid... and somehow we're supposed to work to the user's benefit every single time he tries a new one out? He hasn't had any duds yet... which is frankly unbelievable given he has put stupid shit together like stopping magic with magic and delaying by not swinging a sword.
If this dude is the Hero that MC defeated a few chapters ago, then I hope this time MC kills him or steal all his skills and sell him as slave. That's everything that trash Hero deserves.
