|The user assists an ally by boosting the power of that ally's attack.|
Helping Hand is a move that will increase the damage done by the user's ally this turn by 50%. It will fail if there is no adjacent ally, or if the ally has already acted this turn.
It can still affect an ally behind a substitute or in the semi-invulnerable turn of a move like Fly or Dig.
Helping Hand targets the user.
