Best Hit Points Effort Values Training Spot
If you're looking to boost your Pokemon's Overall Hit Points Stat through Effort Value (EV) training, look no further than Route 10. If you use the Super Rod on the waters on this route, there is a 50% chance of a Slowpoke appearing. And every Slowpoke you defeat will give you 90 EVs towards your Hit Points Stat. Poliwhirls will appear the other 50% of the time, giving you 65 EVs for each defeat. Since these Pokemon have a constant appearance rate, a player can literally use the Super Rod over and over and abuse this in order to get their Pokemon a better Overall Hit Points Stat.
Players can also use the item HP UP to boost their Pokemon's Hit Points EVs, increasing the EV Stat by 2,560 until the first 25,600 Effort Values are reached for the stat.
