Whirlpool is a damaging Water-type move that traps the target for 4-5 turns. It will prevent the target from switching out or escaping, and it will also damage the target for 116 of their maximum HP each turn for the duration of the attack. The effects of Whirlpool will be negated if Rapid Spin is used by the afflicted Pokémon. In a wild Pokémon battle, the active Pokémon can still flee from battle if it is holding a Smoke Ball. Whirlpool will deal double damage to Pokémon that are in the middle of using Dive.
