## Critical hit – bulbapedia, the community-driven pokémon encyclopedia hp gas online login

When a move lands a critical hit, the attacker’s level will be doubled during damage calculation, which approximately (but not quite) doubles the damage dealt. A rough formula for the damage multiplier is (2L+5)/(L+5) where L is the attacker’s level; as a result, lower-leveled Pokémon have a smaller critical hit boost than higher-leveled Pokémon. For example, a level 5 Pokémon will inflict about 1.5× damage on a critical hit, while a level 20 Pokémon will inflict 1.8× and a level 95 Pokémon will inflict 1.95×.

Critical hits ignore all stat stage modifiers and the halved Attack from burn. This includes beneficial stat modifiers as well, making it possible for a critical hit to deal less damage than a non-critical hit if the attacker has at least doubled their Attack/ Special or the target’s Defense/Special is at least halved.

Whether a move scores a critical hit is determined by comparing a 1-byte random number (0 to 255) against a 1-byte threshold value (also 0 to 255); if the random number is less than the threshold, the Pokémon scores a critical hit. If the threshold value is T, then this means the probability ( P) of scoring a critical hit is P = T / 256. (Note that this means it is impossible for a critical hit to be guaranteed; there will always be a 1/256 chance that a critical hit will not be scored.)

At all times, the maximum value for T is 255 (which equally means the maximum value for P is 255/256). All operations that factor into T are also integer operations (meaning divisions are **rounded down** to the nearest whole number). (Note that the division in P = T / 256 is not rounded.) Due to the process the game uses to compute T, BaseSpeed is also effectively *rounded down* to the nearest even number.

As with the core games, the maximum value for T is always 255 (or 255/256 for P) and any divisions that factor into T are *rounded down* to the nearest whole number. Due to the process the game uses to compute T, BaseSpeed is also effectively *rounded down* to the nearest multiple of 4.

In Generation II, when a move scores a critical hit, all stat stage modifiers, the halved Attack from burn, and the defensive boosts from Light Screen and Reflect are ignored if the target’s defending stat stage ( Defense or Special Defense) is greater than or equal to the attacker’s attacking stat stage ( Attack or Special Attack). From Generation III onwards, when a move scores a critical hit, the attacker’s negative stat stages, the defender’s positive stat stages, and the defensive boosts from Light Screen, Reflect, and Aurora Veil are always ignored. However, the halved Attack from burn is no longer ignored.

The probability of landing a critical hit is no longer based on the attacker’s base Speed, but rather is based on a fixed formula for all Pokémon. Similar to stats, there are temporary in-battle stages used to determine the probability that a particular move will be a critical hit.

Note that it is possible for a Pokémon to acquire the effect of a Lansat Berry even if it is already holding another item, through the use of Baton Pass, Pluck, Bug Bite, or Fling; or by obtaining another item after consuming the Berry, such as via Thief or Symbiosis.
