Aura Break in Pokémon Ultra Sun & Ultra Moon

The effects of “Aura” Abilities are reversed to lower the power of affected moves.

Makes Dark Aura and Fairy Aura weaken moves of their respective types.

While Dark Aura or Fairy Aura is active, Aura Break reverses the corresponding aura boost: affected Dark- or Fairy-type moves deal approximately 75% of their normal power, a 25% reduction rather than a boost. Without the corresponding aura, Aura Break does not reduce that type’s power.
