Acupressure

Raises one of a friendly Pokémon's stats at random by two stages.

Acupressure raises one the user's stats chosen randomly: Attack , Defense , Speed , Special Attack , Special Defense , accuracy , evasion by two stages.
Acupressure will never choose a stat that is already raised to its limit.
Stats can be raised to a maximum of +6 stages each.
Acupressure can be applied to an adjacent ally and it can not be stolen by Snatch.
Acupressure fails if the target ally is protected by Crafty Shield.
Acupressure targets a field position and will fail if it initially targeted an ally but now targets itself due to position shifting in Triple Battles or Ally Switch.

• In Gen 4 Acupressure can be stolen by Snatch and it fails if the target ally (but not the user) is behind a Substitute.
