Im EV training an Archen in Attack on Route 1, and i fainted a Pokemon and leveled up twice. i was holding the Power Bracer, so would i get 10 EVs, or just the five?
Level doesn't affect EVs at all. All of the Power Items give x + 4 EVs, so if that Pokemon gave 1 EV and you leveled twice, it would only be 5 EVs. You would only gain 10 EVs with the aid of Pokerus.
