Delta Stream in Pokémon Omega Ruby & Alpha Sapphire

Affects weather and eliminates all of the Flying type’s weaknesses.

Creates strong winds that remove the Flying type’s weaknesses.

Creates strong winds, making the Flying type’s weakness contribution neutral. A dual-type Pokémon’s other type still affects damage, so a hit can remain super effective. Ordinary weather cannot replace strong winds, but Desolate Land or Primordial Sea can. Strong winds remain while any active Pokémon retains Delta Stream, and end when none does. Air Lock and Cloud Nine suppress the wind effects; Stealth Rock and Anticipation are unaffected.
