Amber Button
Either there's something wrong with the translation or MC is legit retarded. He just got an appraisal with no apparent limit, immunity to mental effects and the means to evolve any and all fey including ones that thus far were deemed impossible to evolve while gaining their abilities in the process and MC (who runs a fey shop BTW) instantly deems it useless. He just acquired the most absurd cheat he could possibly have in the pokemon-esque world he lives in and disappointment is what he feels. I can already see how author is going to use this as a means to hype MC intelligence by making a big deal out of it when he discovers just how obscenely OP the fey with absurd level starting stats really is....
