Delta Stream (ability)

Effect

Delta Stream creates strong winds when the ability is activated (by Rayquaza Mega-Evolving).

Strong winds have the following effects:

  • The weather stays active as long as the ability-bearer remains in battle, but stops when the Pokémon is switched out.
  • Electric-, Ice-, and Rock-type moves deal normal damage to any Flying-type Pokémon in battle instead of being super-effective.
  • The strong winds cannot be replaced by a regular weather condition - in other words the moves Hail, Rain Dance, Sunny Day, and Sandstorm, and the abilites Drizzle, Drought, Sand Stream, and Snow Warning will fail.

The abilities Cloud Nine or Air Lock are still able to bypass the effects of Delta Stream, but Mold Breaker is not.
