How exactly do type berries, like Yache or Charti Berries, interact with multi-hit moves? Does it reduce the damage for every attack or just the first one one? As an example, if you gave a Swampert a Rindo Berry and it was hit by a Bullet Seed, would the Rindo berry reduce the damage done by each of the up to five hits or would it only reduce the damage of the first seed to strike?
