Boosts the power of a move used consecutively by the holder. The Metronome boosts the power of a move by 10% (in Generation IV) or 20% (from Generation V onward) for each previous, consecutive turn it has been used successfully, up to a maximum increase of 100%. If the Pokémon is switched out, uses a different move, or uses the move unsuccessfully (such as targeting into Protect or into an immunity), the bonus is reset to 0%.
Since the Metronome counts the number of uses of a move, multi-strike moves only increase the counter once per use regardless of the number of strikes.
If a Pokémon uses a move that calls another move, the move that it turns into is what's taken into account when determining whether the bonus should accumulate or reset.
If a Pokémon uses a move with a charging turn, that move is considered to be successfully used during the charging turn, and will accumulate a boost that applies to the attacking turn.
Generation IV
The Metronome boosts the power of a move by 10% for each previous, consecutive turn it has been used successfully, up to a maximum increase of 100% (which requires using the same move 11 or more times in a row).
Generation V onward
The Metronome now boosts the power of a move by 20% for each previous, consecutive turn it has been used successfully, up to a maximum increase of 100% (which requires using the same move 6 or more times in a row).
