I need a faster way to level up. The only thing I have left to do is dev island, but all of the trainer’s pokemon are lvl 120. My pokemon lvl is 103-105. The level trainer in the secret base only raises it about a level per round with the lucky egg.
Once you get above level 100, I would just grind money at Sonata Tracks, buy vitamins, and then go to la feu to cook rare candies.
