Various ID Notes - 3rd Generation - R\S\E\FR\LG

Values derived from a Pokemon's ID

Each Pokemon comes with a 32 bit identifier, generated at random, which determines significant information about the uniqueness of the Pokemon.

Nature

The ID modulo 25 identifies the nature of a Pokemon. Shown here are the taste preferences of Pokemon with those natures (what PokeBlocks they like), and the stats to increase and decrease.

 Hex = Nature (Like, Dislike) +Stat increase, -Stat decrease
 00 = Hardy [neutral]
 01 = Lonely (Spicy, Sour) +Attack, -Defense
 02 = Brave (Spicy, Sweet) +Attack, -Speed
 03 = Adamant (Spicy, Dry) +Attack, -Special Attack
 04 = Naughty (Spicy, Bitter) +Attack, -Special Defense
 05 = Bold (Sour, Spicy) +Defense, -Attack
 06 = Docile [neutral]
 07 = Relaxed (Sour, Sweet) +Defense, -Speed
 08 = Impish (Sour, Dry) +Defense, -Special Attack
 09 = Lax (Sour, Bitter) +Defense, -Special Defense
 0A = Timid (Sweet, Spicy) +Speed, -Attack
 0B = Hasty (Sweet, Sour) +Speed, -Defense
 0C = Serious [neutral]
 0D = Jolly (Sweet, Dry) +Speed, -Special Attack
 0E = Naive (Sweet, Bitter) +Speed, -Special Defense
 0F = Modest (Dry, Spicy) +Special Attack, -Attack
 10 = Mild (Dry, Sour) +Special Attack, -Defense
 11 = Quiet (Dry, Sweet) +Special Attack, -Speed
 12 = Bashful [neutral]
 13 = Rash (Dry, Bitter) +Special Attack, -Special Defense
 14 = Calm (Bitter, Spicy) +Special Defense, -Attack
 15 = Gentle (Bitter, Sour) +Special Defense, -Defense
 16 = Sassy (Bitter, Sweet) +Special Defense, -Speed
 17 = Careful (Bitter, Dry) +Special Defense, -Special Attack
 18 = Quirky [neutral]

Gender

 If Pokemon species is...    Range of female
  12.5% female                0-30
  25% female                  0-63
  50% female                  0-126
  75% female                  0-190

Unown shape

A=(id>>24)&0x03;
B=(id>>16)&0x03;
C=(id>>8 )&0x03;
D=(id    )&0x03;
Unown=D|(C<<2)|(B<<4)|(A<<6);

Wurmple

If a Wurmple's ID modulo 10 is greater than or equal to 5, it will evolve into Cascoon; else Silcoon.

Ability

If a Pokemon's ID number is even, it has the first ability possible for that species; else the second ability.

Effort Values & Effort Points

Individual Values

Stats

HP = int((int((A*2+B+int(C/4))*D/100)+D+10
Other Stats = int((int((int((A*2+B+int(C/4))*D/100)+D+5)*E)

where:

• A = Pokemon's Base Stat
• B = Pokemon's Individual Value
• C = Pokemon's Effort Value
• D = Pokemon's Level
• E = Normally equal to 1.

As an exception, Shedinja's HP is always 1 (its Base HP is 1).

Hidden Power

HP Type = round((A+B+C+D+E+F)*15/63)

• A through F are initially 0.
• If HP IV is odd, A=1.
• If Attack IV is odd, B=2.
• If Defense IV is odd, C=4.
• If Speed IV is odd, D=8.
• If Special Attack IV is odd, E=16.
• If Special Defense IV is odd, F=32.

HP Base Damage = round((A+B+C+D+E+F)*40/63)+30

• A through F are initially 0.
• If BIT1(HP IV) is 1, A=1.
• If BIT1(Attack IV) is 1, B=2.
• If BIT1(Defense IV) is 1, C=4.
• If BIT1(Speed IV) is 1, D=8.
• If BIT1(Special Attack IV) is 1, E=16.
• If BIT1(Special Defense IV) is 1, F=32.

Encounters

Each area has a probability of Pokemon appearing, expressed as a value of 1, 4, 9, 10, 20, 25, 30, and 35. Whenever the player takes a step in which Pokemon could appear, the game uses this formula:

X = Y * 16

where:

• Y = Encounter value
• If a random number from 0 to 2874 exclusive is less than X, a Pokemon will appear.

Modifications

• If the Mach Bike or Acro Bike is used, multiply by 4/5.
• If the Black Flute had been used, multiply by 1/2. If the White Flute had been used, multiply by 3/2.
• If the first Pokemon in party has a Cleanse Tag, multiply by 2/3.
• If the first Pokemon in party has Stench, multiply by 1/2. If the first Pokemon in party has Illuminate, multiply by 2/3. (In either case, ignore if the Pokemon holds a Cleanse Tag.)

Damage

Experience

Whenever a Pokemon defeats another Pokemon, it gains Experience points (EXP). The amount of EXP a Pokemon is worth is based on a formula which has remained constant among all Pokemon versions.

Two growth rates were added in Ruby and Sapphire: their maximum experience values are 600,000 and 1,640,000.

See the Experience table.

Trainer ID

Critical Hit Method

• Set C to 0
• If Focus Energy is in effect for attacker, add 2 to C.
• If attack is one marked as "good chance for a Critical Hit", add 1 to C.
• If attacker is Chansey with Lucky Punch, add 2 to C.
• If attacker is Farfetch'd with Stick, add 2 to C.
• If attacker has Scope Lens attached, add 1 to C.
• The critical hit ratio is as follows:
  • C = 0: 1/16
  • C = 1: 1/8
  • C = 2: 1/4
  • C = 3: 1/3
  C = 4 or more: 1/2

Notes on breeding

Species

1. One of the Pokemon can be a Ditto, but not both. The baby will be the species that isn't the Ditto. For the purposes of breeding, the Ditto will have the gender that the other isn't.
2. The species hatched from a Nidoran(f) is either Nidoran(m) or Nidoran(f).
3. The species hatched from an Illumise is either Illumise or Volbeat.
4. If neither parent is holding a Lax Incense and the baby species would be Wynaut, the baby species is Wobbuffet instead.
5. If neither parent is holding a Sea Incense and the baby species would be Azurill, the baby species is Marill instead.
