|Steel Wing Move Details|
Steel Wing is a damage-dealing move that carries a secondary effect. In battle, Steel Wing has a 10% chance of raising the user’s Defense stat by one stage.
As the move’s name suggests, Steel Wing is usually learned by Flying-type Pokémon. Because of this, Steel Wing can be used as a coverage move against Rock-type Pokémon.
Steel Wing doesn’t see any use in competitive play.
With a relatively low base power and 90% accuracy, Steel Wing isn’t a very reliable move.
In a main story playthrough, however, Steel Wing is a viable option early in the game. The move packs enough power to beat weaker opponents. You can consider Steel Wing an option as a coverage move for your party’s Flying-type Pokémon.
Although this move will fall off towards the middle and late game. The move won’t be particularly powerful against stronger Pokémon. Likewise, Steel Wing’s 90% accuracy is a bit unreliable.
Most Flying-type Pokémon will also have access to better coverage moves at higher levels.
