Max-Geyser is a Water-type Max Move introduced in Pokémon Sword and Shield. Max Moves don't have traditional power or accuracy stats because they replace other moves when a Pokémon Dynamaxes. The move power is determined by the base move’s strength, typically ranging from 100 to 150. Max-Geyser sets up the Rain weather condition for five turns, which boosts the power of Water-type moves and weakens Fire-type moves. This makes Max-Geyser strategically valuable in altering the battlefield conditions in favor of Water-type Pokémon.
