Default A Guide to EV Training for the Fourth and Fifth Generations of Pokemon

A Guide to EV Training for the Fourth
and Fifth Generations of Pokemon


When it comes to competitive battling, few things are more important than the correct use of Effort Values, of EVs for short. However for the most part these secret mechanics are barely mentioned as you play through the game, and certainly aren't explained in any real detail. This guide will teach you about what EV training is, how to do it, tips on how to get it done quickly and easily, and some handy spots where you can get your EV training done.

Effort Values, an Introduction

EV training is the act of adding effort values onto your Pokemon. But what are effort values? EVs come in two forms;
Effort Values that are given: Each Pokemon has its own specific value attached to it, and a stat that corresponds to that number. The number ranges from 1 to 3, and all six stats are covered. When you defeat a Pokemon in battle, that particular value is added to a pool of effort values that your Pokemon has obtained.
Effort Values that are obtained: As mentioned above, when a Pokemon defeats another it gains Effort Value Points, which are then placed in a pool of all the EV Points it has gained. It is adding points to this pool that increases the stats, and is detailed further below.

So, as you battle more and more Pokemon, you gain more and more EV Points. But what do they do? This where numbers start getting involved. A Pokemon can obtain a maximum of 510 EVs across all of its stats, but only a maximum of 255 EVs in a single stat at a time. Every time a Pokemon gains 4 EV Points in a single stat, that stat itself is increased by 1 point. Now as a Pokemon can gain up to 255 EV Points in a single stat, this translates to 64 stat points. This is why EV training is so useful, it allows you to get your stats anywhere up to 64 points higher than if you didn't EV train!

This is the main reason dedicated EV trained Pokemon are superior than non-EV trained Pokemon. If people pay no heed to where there EVs are going (Like we all do when we are simply facing the gym challenge), then you end up wasting EVs on stats you will never make use of. Take Alakazam for example, a very speedy-but-frail special attacker. If you didn't pay attention to EV training, then you'd be very likely to end up with a lot of EV Points in unneeded places like its physical attack stat and defences, when they could be invested in making it an even stronger or faster special attacker! In this sense it's just as important to watch where you're EVs are not going.

How to EV Train

The basic methodology of EV training is, at its heart, extremely simple, you battle! However as mentioned previously, it is simply an act of only battling the correct Pokemon, those that give EVs in the stat you require. Luckily this has all been discovered by accessing the games code, and we now know exactly which Pokemon give which EVs and how many of them. Follow the below links to learn who gives what;
Pokemon that give HP EVs Fourth Gen and Fifth Gen
Pokemon that give attack EVs Fourth Gen and Fifth Gen
Pokemon that give defence EVs Fourth Gen and Fifth Gen
Pokemon that give special attack EVs Fourth Gen and Fifth Gen
Pokemon that give special defence EVs Fourth Gen and Fifth Gen
Pokemon that give speed EVs Fourth Gen and Fifth Gen

So long as you make sure you seek out and battle only these Pokemon, you can ensure that your EVs go only into the stats you want them to. However there's a couple of tips that will help you make the most out of your EV training;
Ensure the EVs you obtain are divisible by four in each stat: The old saying "every little helps" is quite fitting in this context. While a single EV may seem negligible in comparison to the 510 you potentially gain, wasted EVs in one area can deprive other stats of valuable boosts. And the simple, most effective method of ensuring you don't waste these points is to ensure you give each of your Pokemon training that results in their total EVs for each stat divides by four. Since it's only every four points that a stat increases, this means that any extra have no effect on the stat whatsoever. It is for this reason that while it may seem like the logical thing to pour the maximum 255 EVs into a stat, it is actually rather inefficient as it is no better than 252, the largest multiple of four obtainable in a single stat.
Keep a tally: While EV training itself is an extremely simple process in of itself, it can be very difficult to keep track of your progress if you aren't paying attention! There is no way of checking how many EVs you already have in each stat in the game, meaning you have to keep track externally. While not as worrying if you are simply maxing out two stats, it's very important to keep track if you plan on placing EVs in three or more stats where precision placement is necessary. The simplest way is a simple tally chart done with pen+paper, adding a new line every time you encounter the Pokemon you wish to face. A physical copy is also safer than using an online counter, since that runs the risk of crashing or being reset accidentally. Whichever way you go about it, keeping track of your progress is very important.

Items that Speed EV Training Up

While EV training can be a surprisingly quick process if done efficiently, there are means of making it even quicker, the simplest of which is to use items. EV-boosting items come in two flavours, those that increase the EV output of a battle, and those that simply give you EVs;
The Power Items: These held items cover the former, in that they increase the amount of EVs you gain from each battle. There are six Power Items, one for each stat, and each gives 4 EVs (Which of course means one stat point) in that stat every time you knock an opponent out. These items can be employed in two ways. First, you can attach a Power item and battle Pokemon which give EVs in the same stat for huge amounts of EVs in that stat, anywhere up to 7 per battles. Alternatively you can attach a Power item for one stat, and defeat Pokemon who give EVs in another. This effectively lets you EV train in two stats simultaneously, assuming you can keep track of how many you're gaining in each this can be a very effective method.
The Macho Brace: Another item that increases EV output, this one functions a little differently to the Power items. Rather than adding a set quantity of EVs to a certain stat, it doubles the EVs gained at the end of each battle. On one hand, this can be inferior given that if you're facing Pokemon that only yield one EV point, you will only gain two in comparison to the five you would gain with the relevant power item. However it is a better choice if you are training for multiple stats in a single patch of grass, providing a consistent doubling to all boosts rather than a big increase to one. However its main perk is that it stacks with something called the Pokerus, which I will come to later on.
Note; One thing to note when using these two items is that they halve you speed stat while battling, meaning they may be unsuitable for training against foes you need to hit first to win. For example fishing for Seaking and Gyarados is a great way of gaining attack EVs, but a frail Infernape will not appreciate having to take a super effective Water attack before it gets a chance to defeat them!

The Vitamins: These items cover the latter, in that upon consumption 10 EVs are added to a single stat depending on the vitamin, it's that easy! However a replacement for EV training they are not, for several reasons. First and foremost, once a Pokemon gains 100 EV points in a stat, vitamins can no longer be used on that stat. Not a problem for mixed EV spreads, but a simple 252/252 spread will only get minimal use out of each. Next, they are extremely expensive to buy, at 9800 apiece. Buying large quantities is not something most trainers will be able to do until after beating the Elite Four several times.
The Wings: New to the Fifth Generation are the Wings, almost like a "lite" version of the Vitamins. Just like the vitamins, there is one for each stat and they simply add a one-off EV value upon consumption. However the yield is far smaller, giving only a single EV at a time. However they do come with one advantage, in that there is no cap on how many EVs a Pokemon can have before they stop working. While hardly economical for training entire teams with (They cannot be bought and it would take massive amounts of time to gather enough just to raise a single Pokemon), they can be extremely handy for bumping a stat up to the exact value you want it rather than having to fly to a whole other area to face a Pokemon that yields the desired value.

Details on the locations of the Power Items and Macho Brace, Vitamins, and Wings can be found at these links.

The Pokerus

There is one other method of increasing the EV output of a battle, but it is not an item, but instead a very special "status condition" called the Pokemon Virus, or Pokerus for short. Contrary to the name this is not a bad thing at all, but instead a boon to have while EV training!
The Pokerus acts similarly to the Macho Brace, in that it doubles the output of EVs from battle. The great thing about the Pokerus is that this doubling is applied after other modifiers have been calculated, which can lead to some insane EV outputs. For example, a Pokemon could be using a Power Bracer, which adds 4 attack EVs on at the end of each battle, and facing a Seaking, who gives 2 attack EVs itself. Upon defeating it, the Pokerus would double the 6 EVs normally gained, reaching a huge 12 points! Alternatively you could use it to stat with the Macho Brace for quadrupled EVs, again not capable of the dizzying highs the Pokerus/Power Item combo can reach but more suited to easily raising multiple stats simultaneously. It has no effect on Vitamins or Wings, however.
Pokerus is obtained by defeating a wild Pokemon which has the virus, which is determined in a similar way to shinyness. However Pokerus is far rarer, with each encounter having roughly a 1 in 22,000 chance of being infected. However with the advent of online trading forums (Such as our own PE2K) and the GTS, obtaining it this way is far simpler. After obtaining a Pokemon with the Pokerus, you can proceed to spread it to the rest of your team. Think of it as a Pokemon Pox Party (Where parents take their young children to play with a child infected with chicken pox, in order for them to catch and recover from it young rather than risk them facing it as an adult, which is very often lethal), if you will. After each battle, any Pokemon next to an infected Pokemon stands a chance of being infected themselves. Through this method you can rapidly infect entire teams of Pokemon to increase the speed at which you can EV train them.
An infected Pokemon is "cured" of the Pokerus automatically after a period of around two-three days, although it appears to be shorter in Pokemon Black and White. However only the ability to spread the virus is lost, the doubling of EVs is luckily a permanent gain! It is for this reason many people designate one Pokemon an "infector" a Poke used explicitly for spreading the virus. This is acheived by infecting the desired Pokemon and immediately placing them in the PC, which stops the Pokerus timer until you next withdraw it. This allows you to keep it for many times longer than you normally would, so long as you redeposit it immediately after use and replace it with a new infector regularly.

Frequently Asked Questions
Feel free to submit your own!

I'm following your guide like you said, but my stats are hardly rising at all! What gives?

EVs boosts are added every time a Pokemon levels up, so you won't see a change if you don't increase your level. However even upon levelling up, the jumps you see are very random. One level you may gain 10 attack points, the next you may only jump 1! The only time you will see all of your EVs present is when you hit that magical level 100, where all remaining EVs are applied and you see your final stat. As long as you follow the guide, you will se the desired results at the end of your training.

If EVs are only applied when a Pokemon levels up, can I not EV train a level 100 Pokemon?

In Fourth Generation games, unfortunately you cannot. A level-up is needed for any gained EVs to be applied. However in Fifth Generation games, this has been changed so that at level 100, EVs gained will be applied without levelling up.

What happens if I use more than one Pokemon in a battle?

Like exp. points, all Pokemon that take part gain something. However unlike exp, each Pokemon gains the full EVs rather than them being distributed between them (It's awfully difficult to share a single EV!). However any boosts applied to the base gain are limited to the individual, only the Pokemon using a Power Anklet will gain the 4 extra EVs and only the Pokerus-infected Pokemon will have their gains doubled.

Is there any way of removing EV Points from a Pokemon?

Yes, there are a subset of berries that both raise a Pokemon's happiness and reduce the EVs in a single stat by 10 EV points. A reverse-vitamin, if you will. They are:
Pomeg: -10 HP
Kelpsy: -10 Att
Qualot: -10 Def
Hondew: -10 SpAtt
Grepa: -10 SpDef
Tamato: -10 Spe


And there you have it, an introductory guide to EV training! Hopefully you found this informative, and good luck with your endeavours [=
