I'm confused. So if you kill 50 Patrats, that's +5 attack points. Do they show up when you level up? It seems very unlikely that I'm going to keep fighting level 2-10 Patrats until my level 47 Excadrill levels up. I just don't quite understand when the EV's show up. Can I kill a large amount of Patrats and go elsewhere to train to finish leveling it up? Will it lose the EV's?
