Halves the damage the Pokémon takes while its HP is full.
Multiscale (Japanese: マルチスケイルMultiscale) is an Ability introduced in Generation V.
Effect
In battle
Multiscale reduces damage taken from damage-dealing moves by half when at maximum HP. It does not reduce the amount of HP taken from moves that deal direct damage.
When hit with a multistrike move at maximum HP, only the first hit will have its damage reduced. All further hits deal full damage.
In Pokémon UNITE, Multiscale is Dragonite's Ability, after evolving from Dragonair. It reduces the damage received by the user by 20% for 2.5s. This Ability can be triggered every 15 seconds.
