Well, you do know you can change these right? There’s a woman in Channeler in the Celadon City Pokemon center that can determine the nature of all the Pokémon you run into for 24hours. Google Let’s Go fortune teller for the tutorial. Also, you can farm bottle caps to train your IVs once the Pokémon is Lv. 100! My Clefairy was actually missing 2 Best IVs, so I used bottle caps to finish out the other two.oh thats cool I wasted 4 days of my life hunting for a shny Poliwag only to notice it didnt have the ivs and nature I wanted
