Niesel (Drizzle)

Drizzle automatically summons rain when the Pokemon enters battle. The rain persists indefinitely unless replaced by another weather condition. Under rain, Water-type moves deal 1.5x damage, Fire-type moves are weakened to 0.5x, Thunder and Hurricane have perfect accuracy, Solar Beam's power is halved, and Weather Ball becomes Water-type with doubled power.

When multiple weather-setting abilities activate simultaneously (such as at the start of a double battle), they resolve in order of Speed, with the slowest Pokemon's weather remaining active. Trick Room reverses this priority. The ability activates each time the Pokemon enters the field, not just the first time.

Drizzle is found on Politoed, Pelipper, and Kyogre. It forms the backbone of rain-based team strategies, instantly enabling Swift Swim users, boosting Water moves, and weakening opposing Fire teams. Pelipper's combination of Drizzle, U-turn, and support movepool makes it the most common rain setter in competitive play.
