==Type effectiveness== | |||
Since each move has an [[elemental types|elemental type]], its ''effectiveness'' is largely determined by the targeted Pokémon's type. Moves can have regular effectiveness or be super effective, not very effective, or not effective at all. The effectiveness of types against one another has varied among generations, see [[Type chart (Generation I)|this page]] for its [[Generation I]] iteration and [[Type chart (Generation II-present)|this page]] for the current model. | |||
== | ===Super effective=== | ||
{{ | {{redirect|"Super effective"|the webcomic|Super Effective (webcomic)}} | ||
When a move is '''super effective''', it inflicts double the damage it would normally do. For example, a move like {{m|Megahorn}} used against a {{type2|Psychic}} Pokémon will be super effective because {{type2|Bug}} moves are super effective against Psychic-types. This effect can stack up; for example, a Pokémon that is {{t|Rock}}/{{t|Ground}} and is hit by a {{type2|Water}} move like {{m|Surf}} will be damaged four times as much by the move as a {{type2|Normal}} Pokémon would be, because both Rock and Ground Pokémon are weak to Water moves. | |||
===Not very effective=== | |||
When a move is '''not very effective''', it deals half of the damage it would normally do. This works exactly like super effective moves, and can stack up. For example, a {{t|Steel}}/{{t|Rock}} Pokémon will be damaged by a quarter of the amount by a {{type2|Normal}} move. Likewise, a {{t|Normal}}/{{t|Flying}} Pokémon hit by a {{type2|Fighting}} move will be damaged normally, as the super-effectiveness of Fighting against Normal is canceled out by the not-very-effectiveness of Fighting against Flying. | |||
===Not effective=== | |||
When a move is '''not effective''', it does not damage the Pokémon at all and that Pokémon is "immune" to that type. This immunity includes status moves of that type. For example, the {{type2|Electric}} move {{m|Thunderbolt}} will have no affect on a {{type2|Ground}} Pokémon such as {{p|Dugtrio}}. Likewise, using the move {{m|Thunder Wave}} will prove useless and yields a "It '''does''' not affect Dugtrio" (whereas a {{m|Confuse Ray}} that simply missed yields "It '''did''' not affect Dugtrio"). Certain types are immune to specific moves, such as {{type2|Grass}} Pokémon being immune to {{m|Leech Seed}}. | |||
==Critical hit== | |||
A move will sometimes inflict a '''critical hit''' against another Pokémon. This will double the damage done after type effectiveness calculations occur, leading to the possibility of a doubly-super effective move that gets a critical hit to do eight times as much damage as normal. Pokémon with the {{a|Sniper}} ability will triple the damage done during a critical hit rather than double it. Regular moves have a 6.25% chance of scoring a critical hit, but some moves have increased critical hit rates. | |||
The chance of causing a critical hit can be modified by using {{Cat|Moves with a high critical-hit ratio|moves}} or items that increase the critical hit level. | |||

When a move scores a critical hit, damage is calculated based on either the modified or unmodified attack and defense stats, whichever is more advantageous to the attacker.

Another example would be if a team had {{m|Light Screen}} or {{m|Reflect}} on it and the attacker scored a critical on the team with the certain wall; the defense added by the wall would then be ignored, and will do double normal damage. In [[Generation I]], critical hits always ignore stat modifiers, even if this is disadvantageous to the attacker. | |||

Abilities come in a wide variety, and have various effects on damage modification. These affects range from increasing and decreasing the power of moves of a specific [[type]], granting immunities, and even changing the power of moves affected by other damage modifiers. These abilities include: | |||
*{{a|Blaze}}, {{a|Overgrow}}, {{a|Torrent}} and {{a|Swarm}} increase the power of {{type2|Fire}}, {{type2|Grass}}, {{type2|Water}} and {{type2|Bug}} moves by 50% when the user's HP falls below 33%, respectively. | |||
*{{a|Thick Fat}} decreases the damage dealt to the user by opponents' Fire-type and Ice-type moves by 50%. {{a|Heatproof}} decreases the damage dealt to the user by opponents' Fire-type moves by 50%. | |||
*{{a|Levitate}} provides immunity to {{type2|Ground}} moves, and {{a|Soundproof}} provides immunity to sound-based moves. | |||
*{{a|Volt Absorb}} and {{a|Water Absorb}} grant immunity to {{type2|Electric}} and {{type2|Water}} moves respectively, healing the user's HP by 25% instead. | |||
*{{a|Dry Skin}} works in part like Water Absorb, healing the user when hit with a {{type2|Water}} move, but it also heals the user by 6.25% each turn during [[Weather conditions#Heavy rain|rain]]. However, it also causes the Pokémon to receive additional damage from {{type2|Fire}} attacks and receive 6.25% (of its HP stat) damage during [[Weather conditions#Intense sunlight|sunshine]]. | |||
*{{a|Flash Fire}} negates the effect of opponents' Fire-type moves and instead increases the power of the ability's user's own Fire-type attacks. Similarly, {{a|Motor Drive}} negates the effect of opponents' Electric-type moves and instead causes the ability's user's Speed to increase. These abilities include [[status move]]s like {{m|Will-O-Wisp}} and {{m|Thunder Wave}}. | |||
*{{a|Mold Breaker}} removes all ability-based immunities to the user's moves. | |||
*{{a|Scrappy}} removes {{type2|Ghost}} Pokémon's immunity to the {{type2|Normal}} and {{type2|Fighting}} moves of the user. | |||
*{{a|Drizzle}}, {{a|Drought}}, {{a|Sand Stream}} and {{a|Snow Warning}} cause permanent rain, sunshine, sandstorm, and hail respectively. | |||
*{{a|Adaptability}} increases the STAB multiplier for moves of the same type as the user from 1.5x to 2x. | |||
*{{a|Hustle}} boosts the Atk stat of the user by 50%. | |||
*{{a|Pure Power}} and {{a|Huge Power}} both double the user's Atk stat. | |||
*{{a|Technician}} increases the power of the user's moves with base power 60 or less by 50%. | |||
*{{a|Super Luck}} increases the user's critical hit ratio. | |||
*{{a|Battle Armor}} and {{a|Shell Armor}} prevent critical hits being dealt to the user. | |||
*{{a|Sniper}} increases the critical hit damage multiplier from 2x to 3x. | |||

Damage modification is a system of multipliers used to change the damage dealt in a battle. These modifiers affect how the damage is calculated by multiplying the move's base power in various ways. These modifiers range from doubling to halving and even negating the damage done.
Type effectiveness
Since each move has an elemental type, its effectiveness is largely determined by the targeted Pokémon's type. Moves can have regular effectiveness or be super effective, not very effective, or not effective at all. The effectiveness of types against one another has varied among generations, see this page for its Generation I iteration and this page for the current model.
Super effective
- "Super effective" redirects here. For the webcomic, see Super Effective (webcomic).
When a move is super effective, it inflicts double the damage it would normally do. For example, a move like Megahorn used against a Template:Type2 Pokémon will be super effective because Template:Type2 moves are super effective against Psychic-types. This effect can stack up; for example, a Pokémon that is Rock/Ground and is hit by a Template:Type2 move like Surf will be damaged four times as much by the move as a Template:Type2 Pokémon would be, because both Rock and Ground Pokémon are weak to Water moves.
Not very effective
When a move is not very effective, it deals half of the damage it would normally do. This works exactly like super effective moves, and can stack up. For example, a Steel/Rock Pokémon will be damaged by a quarter of the amount by a Template:Type2 move. Likewise, a Normal/Flying Pokémon hit by a Template:Type2 move will be damaged normally, as the super-effectiveness of Fighting against Normal is canceled out by the not-very-effectiveness of Fighting against Flying.
Not effective
When a move is not effective, it does not damage the Pokémon at all and that Pokémon is "immune" to that type. This immunity includes status moves of that type. For example, the Template:Type2 move Thunderbolt will have no affect on a Template:Type2 Pokémon such as Dugtrio. Likewise, using the move Thunder Wave will prove useless and yields a "It does not affect Dugtrio" (whereas a Confuse Ray that simply missed yields "It did not affect Dugtrio"). Certain types are immune to specific moves, such as Template:Type2 Pokémon being immune to Leech Seed.
Critical hit
A move will sometimes inflict a critical hit against another Pokémon. This will double the damage done after type effectiveness calculations occur, leading to the possibility of a doubly-super effective move that gets a critical hit to do eight times as much damage as normal. Pokémon with the Sniper ability will triple the damage done during a critical hit rather than double it. Regular moves have a 6.25% chance of scoring a critical hit, but some moves have increased critical hit rates.
The chance of causing a critical hit can be modified by using moves or items that increase the critical hit level.
| Level | Percentage | Moves |
|---|---|---|
| 1 | 6.25% | Regular moves |
| 2 | 12.5% | Moves with an increased critical hit rate: Slash, Stone Edge etc. |
| 3 | 25% | Moves used by Farfetch'd and Chansey with the Stick and Lucky Punch attached, respectively, or Critical hit moves used in combination with Super Luck |
| 4 | 33.3% | Moves with an increased critical hit rate used by Farfetch'd and Chansey with the Stick and Lucky Punch attached |
| 5 | 50% | Critical hit moves used in combination with Super Luck and a Razor Claw or Scope Lens. |
Scope Lens, Razor Claw, and Super Luck add 1 level each, the Stick adds 2 levels (for Farfetch'd only), the Lucky Punch adds 2 levels (for Chansey only), and Focus Energy adds 2 levels to any Pokémon. 50% is the maximum critical hit ratio, since no situation exceeds it.
When a move scores a critical hit, damage is calculated based on either the modified or unmodified attack and defense stats, whichever is more advantageous to the attacker. For example, an attacker who has used Swords Dance and then makes a critical hit will get the benefit of the increased Attack, while one affected by Charm will use its normal Attack score. Another example would be if a team had Light Screen or Reflect on it and the attacker scored a critical on the team with the certain wall; the defense added by the wall would then be ignored, and will do double normal damage. In Generation I, critical hits always ignore stat modifiers, even if this is disadvantageous to the attacker.
Same-type attack bonus
- Main article: Same-type attack bonus
A move used by a Pokémon that is of the same type as the move itself will do 150% of its normal damage, such as a Template:Type2 move used by a Fire-type Pokémon. Dual-typed Pokémon will receive this bonus for both of their types, and a Pokémon whose type can change in-battle will receive the bonus for whatever type they are when they make the move.
Weather
- Main article: Weather conditions
Template:Type2 and Template:Type2 moves' damage will be modified by rain and sunshine. If Rain Dance causes a downpour, Water-type moves will do 50% more damage and Fire-type moves will do 50% less damage. If Sunny Day causes harsh sunlight, Fire-type moves will do 50% more damage and Water-type moves will do 50% less damage.
Abilities
- Main article: Ability
Abilities come in a wide variety, and have various effects on damage modification. These affects range from increasing and decreasing the power of moves of a specific type, granting immunities, and even changing the power of moves affected by other damage modifiers. These abilities include:
- Blaze, Overgrow, Torrent and Swarm increase the power of Template:Type2, Template:Type2, Template:Type2 and Template:Type2 moves by 50% when the user's HP falls below 33%, respectively.
- Thick Fat decreases the damage dealt to the user by opponents' Fire-type and Ice-type moves by 50%. Heatproof decreases the damage dealt to the user by opponents' Fire-type moves by 50%.
- Levitate provides immunity to Template:Type2 moves, and Soundproof provides immunity to sound-based moves.
- Volt Absorb and Water Absorb grant immunity to Template:Type2 and Template:Type2 moves respectively, healing the user's HP by 25% instead.
- Dry Skin works in part like Water Absorb, healing the user when hit with a Template:Type2 move, but it also heals the user by 6.25% each turn during rain. However, it also causes the Pokémon to receive additional damage from Template:Type2 attacks and receive 6.25% (of its HP stat) damage during sunshine.
- Flash Fire negates the effect of opponents' Fire-type moves and instead increases the power of the ability's user's own Fire-type attacks. Similarly, Motor Drive negates the effect of opponents' Electric-type moves and instead causes the ability's user's Speed to increase. These abilities include status moves like Will-O-Wisp and Thunder Wave.
- Mold Breaker removes all ability-based immunities to the user's moves.
- Scrappy removes Template:Type2 Pokémon's immunity to the Template:Type2 and Template:Type2 moves of the user.
- Drizzle, Drought, Sand Stream and Snow Warning cause permanent rain, sunshine, sandstorm, and hail respectively.
- Adaptability increases the STAB multiplier for moves of the same type as the user from 1.5x to 2x.
- Hustle boosts the Atk stat of the user by 50%.
- Pure Power and Huge Power both double the user's Atk stat.
- Technician increases the power of the user's moves with base power 60 or less by 50%.
- Super Luck increases the user's critical hit ratio.
- Battle Armor and Shell Armor prevent critical hits being dealt to the user.
- Sniper increases the critical hit damage multiplier from 2x to 3x.
- Tinted Lens doubles the power of the user's moves that are not very effective.
- Solid Rock and Filter each reduce the power of super effective moves on the ability's user by one third.
- Wonder Guard reduces the power of the opponent's damaging attacks that are not super effective to zero.
Items
- See also: Type-enhancing item
Some held items increase the power of an attack by a small percentage. Most of these items boost attacks only of a certain type by 20%. Some items can also modify damage by boosting the attacker's offensive stats or the victim's defensive stats. Some berries also weaken an opponent's super effective move.
Other held items that modify damage include:
- Muscle Band boosts physical moves by 10%
- Wise Glasses boost special moves by 10%
- Expert Belt boosts super-effective attacks by 20%
- Life Orb boosts the power of all attacks by 30% (at a cost of 10% HP per damaging move used)
- Metronome boosts the power of moves used repeatedly
Other
A number of other variables can affect the amount of damage caused by an attack.
- If the attacker is burned and their ability is not Guts, their physical damage will be decreased by half.
- In a double battle, moves that hit multiple targets do 75% of the damage they do in one-on-one battles.
- Reflect and Light Screen decrease opponents' physical and special attacks, respectively, by 50% in a one-on-one battle and 33% in a double battle.
Randomization adjustment
Every time a regular attack is executed, the actual damage caused is adjusted by a random multiplier between 0.85× and 1.00×. The probability of each percentage is nonuniform due to integer division rounding, causing an approximately 6% chance for each point between 0.85 and 0.99, but only a 2.5% chance for the full damage.
