IntroductionIntroduction

The Damage Formula is one of the two most important calculations in a Pokémon game (the other one being the Stats Formula). Here, we provide the damage formula for Diamond and Pearl (DP). Note that this formula is not the same as that for the games preceding DP, so don't use it to calculate damage for other games.

I need to immediately thank Peterko for all the testing data he has provided for me. This guide wouldn’t have seen the light of day without all his efforts. He literally triggered the damage formula thousands of times (not an exaggeration) during the game so that I could come up with such a detailed description of it. I cannot thank him enough for his efforts. Thank you Peterko... you are one of the best testers I’ve ever seen!

**Section 1 - The Damage Formula and How to Use It**Here is the damage formula for DP:

Damage Formula = (((((((Level × 2 ÷ 5) + 2) × BasePower × [Sp]Atk ÷ 50) ÷ [Sp]Def) × Mod1) + 2) × CH × Mod2 × R ÷ 100) × STAB × Type1 × Type2 × Mod3

where:

**Level**is the user's current

**level**.

**BasePower**is the move's

**base Power**(after performing all necessary modifiers to it... see Section 2).

**[Sp]Atk**is the user's

**Attack or Special Attack stat**(after performing all necessary modifiers to it... see Section 3). If the move used is physical, the Attack stat is utilized; otherwise, the Special Attack stat is used.

**[Sp]Def**is the foe's

**Defense or Special Defense stat**(after performing all necessary modifiers to it... see Section 4). If the move used is physical, the Defense stat is utilized; otherwise, the Special Defense stat is used.

**Mod1**is the

**first modifier**to the damage formula. See Section 5 for more details.

**CH**is

**3**if the move is a

**Critical Hit**and the user has the

**Sniper ability**,

**2**if the move is a

**Critical Hit**and the user's ability is

**not Sniper**, and

**1**otherwise.

**is the**

**Mod2****second modifier**to the damage formula. See Section 6 for more details.

**R**is

**(Rand × 100) ÷ 255**, rounded down, where Rand is a random whole number between 217 and 255 inclusive with uniform probability. This produces

**a whole number between 85 and 100 inclusive**, but not with uniform probability. See Section 8 for more details.

**STAB**is

**2**if the move is of the

**same type as that of the user**and the user has the

**Adaptability**ability,

**1.5**if the move is of the

**same type as that of the user**and the user's ability is

**not Adaptability**, and

**1**otherwise. This is known as

**Same Type Attack Bonus**(hence STAB).

**Type1**is

**2**if the move is

**super effective**against the first type of the foe,

**0.5**if the move is

**not very effective**against the first type of the foe,

**0**if the move type

**does not affect**the first type of the foe, and

**1**otherwise.

**Type2**is

**2**if the move is

**super effective**against the second type of the foe,

**0.5**if the move is

**not very effective**against the second type of the foe,

**0**if the move type

**does not affect**the type of the foe, and

**1**otherwise (or if

**the foe has only one type**).

**Mod3**is the

**third modifier**to the damage formula. See Section 7 for more details.

It should be immediately mentioned that after successfully performing an operator (an operator being +, -, × or ÷), you need to "round down" the number to the nearest whole number before performing the next one. In simple terms, this means to

**remove all the numbers to the right of the decimal point every time the answer is a decimal before proceeding with the next arithmetic operation**.

If the damage formula's damage is 0 and the foe is not immune to the move used, the damage dealt will be 1 instead. This will happen if, say, a Level 2 Bidoof uses Tackle against a Level 100 Aggron. To paraphrase,

**unless the move does not affect the foe, the minimum amount of damage done is 1**.

The way the formula is written above is such that you can actually ignore all the brackets and proceed from left to right (ignoring the BODMAS rules, so to speak) and still come up with the correct answer.

Let's provide an example here. For the sake of simplicity, we shall assume that Mod1, Mod2 and Mod3 are all 1 in this example.

Say we want to calculate the minimum and maximum damage that a Level 47 Staraptor with 140 Attack stat will deal with the move Aerial Ace against a Roserade with 77 Defense stat.

1) We start with the Level of Staraptor, 47, and multiply it by 2, getting 94.

2) Next, we divide 94 by 5, getting 18.8, which is rounded down to 18.

3) Next, we add 2 to 18, getting 20.

4) Next, we multiply 20 by 60 (the move power of Aerial Ace), getting 1200.

5) Next, we multiply 1200 by 140 (the Attack stat of Staraptor), getting 168000.

6) Next, we divide 168000 by 50, getting 3360.

7) Next, we divide 3360 by 77 (the Defense stat of Roserade), getting 43.636363..., which is rounded down to 43.

8) Next, we multiply 43 by 1 (Mod1 is 1 here), getting 43.***

9) Next, we add 2 to 43, getting 45.

10) Next, we multiply 45 by 1 (assuming that we didn't get a Critical Hit here), getting 45.***

11) Next, we multiply 45 by 1 (Mod2 is 1 here), getting 45.***

12) Next, we multiply 45 by 85 (the minimum number that the random number can be), getting 3825.

13) Next, we divide 3825 by 100, getting 38.25, which is rounded down to 38.

14) Next, we multiply 38 by 1.5 (since Aerial Ace is Flying-type, like one of Staraptor's types is), getting 57.

15) Next, we multiply 57 by 2 (since Aerial Ace is Flying-type, which is super effective against Roserade's first type, Grass), getting 114.

16) Next, we multiply 114 by 1 (since Aerial Ace is Flying-type, which is neutral against Roserade's second type, Poison), getting 114.***

17) Finally, we multiply 114 by 1 (Mod3 is 1 here), getting 114.***

So Staraptor's minimum damage would be

**114**.

For the maximum damage, we do exactly the same steps, except that we multiply by 100 instead of by 85 in Step 12. We get

**134**as the maximum damage if we do that. Try it out. (If you do not get 134, make sure that you have actually rounded down your answer at EVERY step in the calculation.)

Note: The steps marked *** can be omitted, since multiplying by 1 does not change the answer.

**Section 2 - The Base Power and Its Modifiers**The base power of the move might be considered to be simple, but in fact it can change by many things during the battle that can affect it.

So many, in fact, that it can be summarised by the following formula:

BasePower = HH × BP × IT × CHG × MS × WS × UA × FA

where

**HH**is

**1.5**if the move has been boosted by the move

**Helping Hand**by the partner, and

**1**otherwise.

**BP**is the

**base power**of the move. This is usually found easily, like 80 for Energy Ball, 60 for Aerial Ace, etc. Some moves have a variable BP, a list of which is given in Section 2A.

**IT**is the

**item multiplier**. The list of items that affect Base Power, together with their effects, is given in Section 2B.

**CHG**is

**2**if the Pokémon's last move was

**Charge**and this move's type is Electric and

**1**otherwise.

**MS**is

**0.5**if one of the Pokémon in play used the move

**Mud Sport**and this move's type is Electric, and

**1**otherwise.

**WS**is

**0.5**if one of the Pokémon in play used the move

**Water Sport**and this move's type is Fire, and

**1**otherwise.

**UA**is the

**user ability multiplier**. A list of user abilities that affect Base Power, together with their effects, is given in Section 2C.

**FA**is the

**foe ability multiplier**. A list of foe abilities that affect Base Power, together with their effects, is given in Section 2D.

The Base power is calculated from left to right, and is rounded down before the next multiplication is performed. The order of the multiplications is as written in the formula above...

**changing the order might result in the incorrect base power**.

**1**otherwise.

**Lustrous Orb**- IT =

**1.2**if the user is Palkia and the move used is Water or Dragon type, IT =

**1**otherwise.

**Any other item**- IT =

**1**.

*Section 2C - User Abilities that affect Base Power*

The following abilities provide the following numbers to the

**UA**multiplier if the user has one of them:

**Rivalry**- UA =

**1.25**if the user is of the same gender as the targeted Pokémon, UA =

**0.75**if the user is of the opposite gender of the targeted Pokémon, UA =

**1**otherwise.

**Reckless**- UA =

**1.2**if the user uses a recoil move, UA =

**1**otherwise.

**Iron Fist**- UA =

**1.2**if the user uses a punching move, UA =

**1**otherwise.

**Blaze**- UA =

**1.5**if the user uses a Fire move and its current HP is less than 1/3 of its maximum HP (rounded down), UA =

**1**otherwise.

**Overgrow**- UA =

**1.5**if the user uses a Grass move and its current HP is less than 1/3 of its maximum HP (rounded down), UA =

**1**otherwise.

**Torrent**- UA =

**1.5**if the user uses a Water move and its current HP is less than 1/3 of its maximum HP (rounded down), UA =

**1**otherwise.

**Swarm**- UA =

**1.5**if the user uses a Bug move and its current HP is less than 1/3 of its maximum HP (rounded down), UA =

**1**otherwise.

**Technician**- UA =

**1.5**if the user uses a move with BP at most 60, UA =

**1**otherwise.

**All other user abilities**- UA =

**1**.

*Section 2D - Foe Abilities that affect Base Power*

The following abilities provide the following numbers to the FA multiplier if the foe has one of them:

**1**otherwise.

**Heatproof**- FA =

**0.5**if the user is using a Fire move, FA =

**1**otherwise.

**Dry Skin**- FA =

**1.25**if the user is using a Fire move, FA =

**1**otherwise.

**All other foe abilities**- FA =

**1**.

**Section 3 - The Attack and Special Attack stats and their Modifiers**The Attack and Special Attack stats can also be changed throughout the match by various things.

[Sp]Atk = Stat × SM × AM × IM

where:

**Stat**is the normal

**Attack or Special Attack stat**.

**SM**is the

**stat modifier multiplier**. See Section 3A for more information.

**AM**is the

**ability modifier**. See Section 3B for a list of abilities that change the attacking stats.

**IM**is the

**item modifier**. See Section 3C for a list of items that change the attacking stats.

As we said for the calculation of the base power, the above multiplication is also performed from left to right, rounding down before performing the next one.

*Section 3A - The Stat Modifier Multipliers*

Each stat (excluding HP) has a stat modifier which is a whole number between -6 and 6 inclusive. This stat modifier starts from 0 and is changed by various moves like Swords Dance and Defense Curl. Some attacks can also change either the user’s stat modifier or that of the foe as a secondary effect, like Overheat and Shadow Ball.

The effect of SM is the following:

Stat Modifier is -6: SM =

**2/8**

**(0.25)**

Stat Modifier is -5: SM =

**2/7 (0.2857)**

Stat Modifier is -4: SM =

**2/6 (0.3333)**

Stat Modifier is -3: SM =

**2/5 (0.4)**

Stat Modifier is -2: SM =

**2/4 (0.5)**

Stat Modifier is -1: SM =

**2/3 (0.6667)**

Stat Modifier is 0: SM =

**2/2**

**(1)**

Stat Modifier is 1: SM =

**3/2**

**(1.5)**

Stat Modifier is 2: SM =

**4/2**

**(2)**

Stat Modifier is 3: SM =

**5/2**

**(2.5)**

Stat Modifier is 4: SM =

**6/2**

**(3)**

Stat Modifier is 5: SM =

**7/2**

**(3.5)**

Stat Modifier is 6: SM =

**8/2**

**(4)**

A few points:

1)

**Critical Hits**: If the Stat Modifier for Attack or Special Attack is less than zero, SM is made equal to 1 if the attack hits for a Critical Hit. Also, if the Stat Modifier for Defense or Special Defense is greater than zero, SM is made equal to 1 if the attack hits for a Critical Hit.

2)

**Unaware**: If the user has the ability Unaware, SM for Defense or Special Defense of the foe is made equal to 1. If the foe has the ability Unaware, SM for Attack or Special Attack of the user is made equal to 1.

3)

**Simple**: If any Pokemon has the ability Simple, SM conforms to a different chart:

Stat Modifier is between -3 and -6: SM =

**2/8 (0.25)**

Stat Modifier is -2: SM =

**2/6 (0.3333)**

Stat Modifier is -1: SM =

**2/4 (0.5)**

Stat Modifier is 0: SM =

**2/2**

**(1)**

Stat Modifier is 1: SM =

**4/2**

**(2)**

Stat Modifier is 2: SM =

**6/2**

**(3)**

Stat Modifier is between 3 and 6: SM =

**8/2**

**(4)**

*Section 3B - Abilities that change the Attack or Special Attack stat*

Here is a list of abilities that modify the Attack or Special Attack stat of the user, which affect the

**AM**multiplier:

Abilities that affect the Attack stat:

**Pure Power**: AM =

**2**.

**Huge Power**: AM =

**2**.

**Flower Gift**: AM =

**1.5**if Sunny Day is in effect, AM =

**1**otherwise.

**Guts**: AM =

**1.5**if the user is Paralyzed, Poisoned, Burned, or Asleep, AM =

**1**otherwise.

**Hustle**: AM =

**1.5**(and physical moves have 80% accuracy).

**Slow Start**: AM =

**0.5**if the user has been in the battlefield for less than 5 turns, AM =

**1**otherwise.

**Other abilities**: AM =

**1**.

Abilities that affect the Special Attack stat:

**Plus**: AM =

**1.5**if the partner has ability Minus, AM =

**1**otherwise.

**Minus**: AM =

**1.5**if the partner has ability Plus, AM =

**1**otherwise.

**Solar Power**: AM =

**1.5**if Sunny Day is in effect (and loses 1/8 of HP per turn), AM =

**1**otherwise.

**Other abilities**: AM =

**1**.

*Section 3C - Items that change the Attack or Special Attack stat*

Here is a list of items that modify the Attack or Special Attack stat of the user, which affect the

**IM**multiplier:

Items that affect the Attack stat:

**Choice Band**: IM =

**1.5**(the user can't use any other move).

**Light Ball**: IM =

**2**if the user is Pikachu, IM =

**1**otherwise.

**Thick Club**: IM =

**2**if the user is Cubone or Marowak, IM =

**1**otherwise.

**Other items**: IM =

**1**.

Items that affect the Special Attack stat:

**Choice Specs**: IM =

**1.5**(the user can't use any other move).

**Light Ball**: IM =

**2**if the user is Pikachu, IM =

**1**otherwise.

**Soul Dew**: IM =

**1.5**if the user is Latios or Latias, IM =

**1**otherwise.

**Deepseatooth**: IM =

**2**if the user is Clamperl, IM =

**1**otherwise.

**Other items**: IM =

**1**.

**Section 4 - The Defense and Special Defense stats and their Modifiers**Various changes can also be performed to the Defense and Special Defense stats of the foe during a match.

In this case, there aren't many things that can change the Defense or Special Defense stats:

[Sp]Def = Stat × SM × Mod × SX

where:

**Stat**is the normal

**Defense or Special Defense stat**.

**SM**is the

**stat modifier multiplier**. See Section 3A for more information.

**Mod**is a

**modifier depending on a few factors**. These are:

Defense modifiers:

**Metal Powder**: Mod =

**1.5**if the foe is Ditto, is holding the item Metal Powder and has not used the move Transform.

**Marvel Scale**: Mod =

**1.5**if the foe has the ability Marvel Scale and is Paralysed, Poisoned, Burned, Asleep or Frozen.

Special Defense modifiers:

**Sandstorm**: Mod =

**1.5**if Sandstorm is in effect and the foe is of Rock type.

**Soul Dew**: Mod =

**1.5**if the foe is Latios or Latias and is holding the item Soul Dew.

**Metal Powder**: Mod =

**1.5**if the foe is Ditto, is holding the item Metal Powder and has not used the move Transform.

**Deepseascale**: Mod =

**2**if the foe is Clamperl and is holding the item Deepseascale.

**Flower Gift**: Mod =

**1.5**if one of the foes has the ability Flower Gift and Sunny Day is in effect.

**Otherwise**, Mod =

**1**.

**SX**is

**0.5**if the move used by the user is

**Selfdestruct**or

**Explosion**, otherwise it is

**1**.

Again, remember to multiply from left to right and round down after each multiplication.

If there are two simultaneous boosts in Mod,

**first apply the ability boost, and then the item boost**.

If the Defense or Special Defense stat is equal to zero after all these modifiers,

**it becomes 1 instead**.

**Section 5 - The First Modifier to the Damage Formula**This section will explain the function of

**Mod1**, the first modifier to the damage formula.

Mod1 = BRN × RL × TVT × SR × FF

where

**BRN**is the

**Burn**modifier;

**RL**is the

**Reflect/Light Screen**modifier;

**TVT**is the

**2vs2**modifier;

**SR**is the

**Sunny Day/Rain Dance**modifier;

**FF**is the

**Flash Fire**modifier.

**BRN**is

**0.5**if the move performed is physical, the user is affected by the Burn special condition and the user's ability is not Guts, and

**1**otherwise.

**RL**is:

**0.5**if the move performed is physical, the foe has setup a Reflect and the game is 1vs1,

**0.5**if the move performed is special, the foe has setup a Light Screen and the game is 1vs1,

**2/3**if the move performed is physical, the foe has setup a Reflect and the game is 2vs2,

**2/3**if the move performed is special, the foe has setup a Light Screen and the game is 2vs2,

**1**otherwise.

Also, if the move is a Critical Hit,

**RL is made equal to 1 no matter what**.

**TVT**is

**0.75**if the game is 2vs2 and the move used hits more than one Pokemon, and

**1**otherwise.

*Note: These moves don't always hit for 75% damage. Research on what conditions trigger the 75% damage are being carried out.*

**SR**is:

**1.5**if Sunny Day is in effect and the move is of Fire type,

**1.5**if Rain Dance is in effect and the move is of Water type,

**0.5**if Sunny Day is in effect and the move is of Water type,

**0.5**if Rain Dance is in effect and the move is of Fire type,

**1**otherwise.

**FF**is

**1.5**if the user has the ability Flash Fire, was previously attacked by a move that is of Fire type, and is using a Fire move,

**1**otherwise.

Yet again, it must be emphasized that the order of the multiplication must be as written above.

**Section 6 - The Second Modifier to the Damage Formula**This section explains what affects

**Mod2**, the second modifier of the damage formula.

Mod2 = ITM × TT × MF

where

**ITM**is:

**1.3**if the user is holding the item

**Life Orb**,

**1**,

**1.1**,

**1.2**,

**1.3**, ...,

**2**if the user is holding the item

**Metronome**and has used the same move once, twice, three times, four times, ... etc. consecutively,

**1**otherwise.

**TT**is

**2**if the user's ability is

**Tinted Lens**and the move used is not very effective against the foe,

**1**otherwise.

**MF**is

**1.5**if the user is attacking with the move

**Me First**,

**1**otherwise.

The order for the multiplication of Mod2 is not completely clear. What's sure is that the

**item multiplier is done first**. Whether Tinted Lens is activated second and Me First last, or the other way round, is still unclear. Please help us to test this.

**Section 7 - The Third Modifier to the Damage Formula**Finally, we come to the third and final modifier to the damage formula, Mod3.

**Mod3**is:

**1.2**if the user is holding the item

**Expert Belt**and the move used is super effective against the foe,

**0.5**if the foe is holding one of the

**type resisting berries**and the move used is

super effective and of the same type as the type that the berry knocks down.

**0.5**if the foe is holding

**Chilan Berry**and the move used is Normal type,

**0.75**if the foe's ability is

**Solid Rock**or

**Filter**and the move used is super effective against it,

**1**otherwise.

In the case where the foe's ability is Solid Rock or Filter and there's also an item boost (Expert Belt or a type resist berry),

**the Solid Rock/Filter multiplier (x0.75) is performed first, followed by the other multipliers as needed**.

As was already stated in the first section,

That means that the most improbable damage that you are able to deal is the maximum possible damage.

**Section 8 - The Random Value In The Formula**As was already stated in the first section,

**R**is the random number in the formula, which is a number between 85 and 100, but not with uniform probability. This section clarifies which numbers are chosen with which probability:**85, 87, 89, 90, 92, 94, 96 and 98**each have a 7.69% chance of being chosen.**86, 88, 91, 93, 95, 97 and 99**each have a 5.13% chance of being chosen.**100**has only a 2.56% chance of being chosen.That means that the most improbable damage that you are able to deal is the maximum possible damage.

*Section 9 - Exceptional Cases*The ninth and final section will concern moves that do not follow the damage formula to the rule.

1)

**Doom Desire**and

**Future Sight**use a slightly different variation of the damage formula for the calculation of the damage dealt two turns after they are used. They use the Special Defense stat of

**the foe that was targeted when the move was used**.

**Type1 and Type2 are also both equal to 1**irrespective of the type of the Pokémon that is being dealt damage.

2) When

**Spit Up**is used, the variable

**R**in the damage formula (i.e. the random number between 85 and 100) is always taken to be

**100**.

3) There are certain moves that do not use the usual damage formula to determine the damage done to the foe. Here is a list of them, and how to determine the damage dealt by each:

**Bide**- Damage is equal to twice the damage received during the last two turns to the last Pokémon attacking the user.

**Counter**- Damage is equal to twice the damage received from the last Pokémon attacking the user during that turn, if the move used was physical.

**Dragon Rage**- Damage is always 40.

**Endeavor**- Damage is equal to the foe's remaining HP minus the user's remaining HP. It fails if this number is not positive.

**Fissure**,

**Guillotine**,

**Horn Drill**and

**Sheer Cold -**Damage is equal to the foe's maximum HP (even if the foe is behind a substitute, in which case this amount of damage is dealt to the substitute instead).

**- Damage is equal to 1.5 times the damage received from the last Pokémon attacking the user during that turn. Fails if that Pokémon is your partner.**

**Metal Burst****Mirror Coat**- Damage is equal to twice the damage received from the last Pokémon attacking the user during that turn, if the move used was special.

**Night Shade**- Damage is equal to the user's Level.

**Psywave**- Damage is equal to (R + 5) × Level ÷ 10, rounded down, where R is a random whole number between 0 and 10 inclusive with uniform probability, and Level is the user's Level.

**Seismic Toss**- Damage is equal to the user's Level.

**Sonicboom**- Damage is always 20.

**Super Fang**- Damage is equal to half the foe's remaining HP, rounded down. (If this damage is 0, it becomes 1 instead.)

4)

**Pain Split**does not even do damage. The user's remaining HP and that of the foe are averaged and rounded down, and then both are set to this value.
