Flower Shield raises the Defense stat of all Grass-type Pokémon on the field by one stage, except those that are in the semi-invulnerable turn of a move such as Fly or Dig. Flower Shield fails if there are no eligible Grass-type Pokémon.
If powered up by a Fairium Z into Z-Flower Shield, the user's Defense stat rises by one stage.
It boosts the Defense of your party's Grass-type Pokémon.* It boosts the Defense of Grass-type Pokémon among you and your teammates in the same room. The stat returns to normal when you go to the next floor or step on a Wonder Tile.*
