A howling blizzard is summoned to strike the opposing Pokémon. This may also leave the opposing Pokémon frozen.
Blizzard targets all adjacent foes. Before Generation IV, Blizzard targeted all Pokémon adjacent to the user, including the ally. In Generation IV, during hail, Blizzard's accuracy changes to 100%. In Pokémon Diamond and Pearl, Blizzard has a 30% chance to bypass Protect and Detect. In Pokémon Platinum and onwards, Blizzard can no longer bypass Protect or Detect, and during hail, are the only ways to avoid Blizzard. Blizzard does damage and has a 10% chance to freeze the targets solid.
