I have a question about the Berries that decrease EVs. Does the berry reduce the actual stat or just the EV count? For example, would using a Pomeg Berry reduce a Pokemon's HP stat by 2 or 3 points, or just the EV by 10?
It depends on the level the pokemon is and the amount of Ev's the pokemon has. For example if the pokemons full ev trained and on lv 100, the stat will lower for sure(dont know the number it lowers, I think it's random). But if the pokemon is on a low level and hasn't been ev trained a lot, you wont see a difference.
In other words, it lowers the EV's, not the stat.
Btw Hank, if the Pokémon is at lvl 100, with full EV training, it will go down by 2 points from one berry. Another berry will make it go down 3 points.
