Belly Drum is a Normal-type status move.
Belly Drum deducts half of the user's maximum HP (rounded down) from its current HP and, in return, it maximizes the user's Attack stat by raising it to +6 stages, even if the user's temporary Attack bonus stages were below 0 prior to using Belly Drum.
Belly Drum fails if the user's current HP is less than half its maximum, or if the user's Attack is already at +6 (even if the user has Contrary).
If the user has Contrary, its Attack will be lowered to -6 stages (although the message will still say that the user maximized its Attack); even if the user's Attack is already at -6 stages, Belly Drum will deduct HP.
