Restores HP if hit by Water moves.
Water Absorb is an ability that allows the Pokémon to heal 25% of its maximum HP when hit by a Water-type move instead of taking damage. This makes the Pokémon immune to Water-type attacks and provides a strategic advantage in battles against Water-type opponents.
