About the Stats of Pokemon

Stats determine how much a Pokemon's attacks do, how much a Pokemon can withstand attacks from opponents, and if the Pokemon goes first or second during a battle.

Base Stats

Base Stats is the thing that makes the biggest difference in a Pokemon's stats. Each kind of Pokemon has different base stats for HP, Attack, Defense, Special Attack, Special Defense, and Speed. And it determines the range of how high or low a stat is with the IVs and EVs a Pokemon has.

EVs

Evs are an important part of training a pokemon to be as good as they can be. EVs allow you to make a Pokemon better in the stats that you want it to be better in. You get EVs every time you battle and recieve exp. and every Pokemon that took part in the battle gets the same amount of EVs. If you battle a Geodude with your Shellos, your Shellos would gain 1 defense EV because Geodudes give 1 defense EV, but if you battled a Geodude with your Shellos and your Roselia both of them would gain 1 defense EV.

Every Pokemon you battle gives out 1, 2, or 3 EVs and they mostly come from their best stat. Sometimes there are strange cases though like Beedrill gives 2 EVs in attack and 1EV in sp.defense or like Yanmega gives 2 EVs in attack.

If your Bronzor beats 4 Geodudes when it levels up it will get 1 more defense point added on than if it had battled 3 Geodudes and a Zubat because Zubat gives 1 speed EV. All of this is because soon as you get 4 EVs in a certain stat and level up it gains 1 more point into that stat. But there is a limit of how many EVs you can get in all, you can only get a total of 510 EVs, but only 255 EVs in one stat so you can't get 999 in a certain stat. Your Pokemon can only get there stats raised by 63 points in one stat.

Some may think that 510 battles is a lot, but there are many ways to make EV training a lot easier. The Macho Brace is one of them it doubles the amount of EVs you recieve so instead of 1 it's 2, instead of 2 it's 4, and instead of 3 it's 6. Also, there is the elusive Pokerus which also does the same thing as the Macho Brace and when they are combined you get 4 times the amount of EVs. And now in D/P there are power items that adds 4 EVs onto a certain stat each time you defeat a pokemon.
The power items are

  1. Power Weight-raises HP
  2. PowerBracer-raises Attack
  3. Power Belt-raises Defense
  4. Power Anklet-raises Speed
  5. Power Lens-raises Special Attack
  6. Power Band-raises Special Defense

Good places to EV train in D/P.

Use the VS. seeker on the cowgirl below Solaceon Town( she has 5 Bidoof and you will get 5 EVs each battle) Route 214 battle Bibarel 2EVs and Kricketune 2EVs or Lake Valor, super rod, Seaking 2EVs and Gyarados 2EVs Oreburgh Mine, there are Geodude 1EV and Onix1 EV here( run from Zubats) Old Chateau Gastly 1EV and Haunter 2EVs Surf anywhere Tentacool 1EV and Tentacruel 2EVs Use VS. Seeker on fisherman with Magikarp's on Route 205 6EVs a battle

IVs

IVs make every Pokemon different from each other and make a big difference in a Pokemon's final stats. Each Pokemon gets a set amount of IVs in each of their stats. Ech Pokemon gets 0 to 31 IVs in each stat. 0 raises your stat by 0, 1 raises your stat by 1, 2 raises your stat by 2, 3 raises your stat by 3, etc. The equation for finding IVs is:
IV = ((Math.Ceiling(Stat / Personality Value) - 5) x 100 / Level) - 2 x Base Stat – Math.Floor(Effort Points / 4)

Math.Ceiling means round up an Math.Floor means round down. This equation works for all stats except HP.

This equation is for HP:
IV = ((Stat - Level - 10) x 100 / Level) - 2 x BaseStat - Math.Floor(EV / 4)

Personality value is based on the Pokemon's nature, if the nature raises a stat it = 1.1, if it has no effect on the stat it = 1, if it lowers the stat it = .9.

IVs also determine what type of Hidden Power the Pokemon has and how powerful it is. Hidden Power can be any type and can have a power between 30 and 70.

the equation for finding Hidden Power:
Hidden Power Type = (T1 + T2 + T3 +T4 + T5 + T6) x 15 / 63
If the IV of your HP is odd, T1 = 1
If the IV of your Attack is odd, T2 = 2
If the IV of your Defense is odd, T3 = 4
If the IV of your Speed is odd, T4 = 8
If the IV of your Special Attack is odd, T5 = 16
If the IV of your Special Defense is odd, T6 = 32
If an IV is even then it = 0

After doing that equation you will get a number between 0 and 15.
0=Fighting
1=Flying
2=Poison
3=Ground
4=Rock
5=Bug
6=Ghost
7=Steel
8=Fire
9=Water
10=Grass
11=Electric
12=Psychic
13=Ice
14=Dragon
15=Dark

to find the power of Hidden Power:
Hidden Power Power = (P1 + P2 + P3 + P4 + P5 + P6) x 40 / 63 + 30

If IV of HP divided by 4 has a remainder of 2 or 3, P1 = 1
If IV of Attack divided by 4 has a remainder of 2 or 3, P2 = 2
If IV of Defense divided by 4 has a remainder of 2 or 3, P3 = 4
If IV of Speed divided by 4 has a remainder of 2 or 3, P4 = 8
If IV of Special Attack divided by 4 has a remainder of 2 or 3, P5 = 16
If IV of Special Defense divided by 4 has a remainder of 2 or 3, P6 = 32
If the IV is divided by 4 and doesn't have a remainder of 2 or 3 it = 0

That will give you the power of your Hidden Power.
