( [2 from mon] + [8 from Power Item] ) * [2 from Pokerus] = 20. Power items grant 8 instead of 4 EVs as of Gen 7.I was EV Training a Corviknight today with Pokerus and a Power Item. Based on my math, defeating a Pokemon that yields 2 EVs would total to 12 EVs (2 plus 4 from the Power Item plus 6 from Pokerus). However when I was checking Corviknight's stats, I was earning 20 EVs per battle. Where did the extra 8 EVs come from?
