Correct, unless the mentor is already EV trained, which isn’t uncommon. If the mentor had all 510 distributed, it wouldn’t receive anymore because it is maxed. In fact, it is highly recommended that a “mentor”, if one is needed, is of really high level (75+ is usually sufficient) and fully EV trained, knowing at least one move that assures a OHKO against whatever hive you’re facing. If you’re just now starting EV training, the mentor can be not trained in specific stats and still own because in-game opponents (especially wild Pokémon) are particularly easy. 🙂

^^ The above is supposed to be a question

And your “mentor” pokemon Would gain the regular EVs it would earn without the boost unless they are holding a boosting item

Yes, that would be correct. The Exp. Share in no way cuts down the EVs you gain. In that regard, it treats the holding Pokémon as though it participated. Further, IF your Emboar was not fully EV trained, your Joltik would STILL get 2 EVs from one Petilil, because the number of EVs a Pokémon yields is given each Pokémon participating, with no divisions. The only possible difference would be if one Pokémon was holding the Macho Brace or a Power Item for that stat, or had the PokéRus, whilst the other participant did not have these advantages, in which case the infected and/or EV-boosting item wielder would receive however many EVs the opponent yields modified by any applicable boosters, and the disadvantageous one would only receive the yield itself.

In short, every one of your Pokémon that participates in defeating a single other Pokémon (Exp. Share wielders included) will receive AT LEAST the individual opponents’ EV yield (excluding Battle Frontier/Subway), and unlike Exp., EVs will NOT be divided based on how many Pokémon took part, largely because the maximum yield is 3 EVs total, and the game has no clear way to determine whether or not you used boosters (the equations do that for it) in order to make sharing EVs possible.

So yeah. Have at it, that Joltik will get 2 Sp. Atk EVs (due to PokéRus) from every Petilil that Emboar defeats. However, force Joltik to fight the Petilils on its own and make it hold the Power Lens (trains Sp. Atk), and you’ll instead get 10 EVs per Petilil–if the Joltik is too weak, send it out first holding the Power Lens, then shove in your Lv. 100 beast and have it kill the thing for Joltik. Joltik will still get the extra EVs obtained through applicable boosters along with the base yield.

Hope this helps. 🙂

I was going to ask the same question and no one seems to have an answer for that either 🙁

@jahu: Hey there!

@Belmad: Yes you do. You get EVs from every Pokémon you defeat, not just from each trainer. Sole exceptions include Battle Frontier/Subway facilities and competitive multiplayer, because you don’t even get EXP in those battles. 🙂

I really don’t get why people think EVing is hard. EVing can be done in the matter of an hour by the time this series will be done. It’s really easy.

But, don’t I get EV by battling normally.
