Apologies. Must've overlooked it when editing it earlier. I believe it's fixed now.Missing part of this guid is in the first spoiler of Road 4.
Just beating Pokemon in the Victory Road exit will level you up quick. If you don't have access to that, the bottom level of Seafoam Island is good for money + EXP.How do I train my Pokemony to the 80+ level if I have it to the 67th level?
