Best Defense Effort Values Training Spot
If you're looking to boost your Pokemon's Overall Defense Stat through Effort Value (EV) training, look no further than Route 6. If you use the Super Rod on the waters on this route, there is a 50% chance of a Shellder appearing. And every Shellder you defeat will give you 100 EVs towards your Defense Stat. Krabby will appear the other 50% of the time, giving you 90 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 Defense Stat.
Players can also use the item Iron to boost their Pokemon's Defense EVs, increasing the EV Stat by 2,560 until the first 25,600 Effort Values are reached for the stat.
