Sweet spot

A sweet spot is the part of an attack that deals more damage or knockback than other parts of the attack. Inversely, the sour spot of an attack does less damage or knockback than the sweet spot.

This is generally due to a certain hitbox of an attack that does more damage than the others, although some sweet spots come about at a certain timing, such as 's forward aerial.

While for the most part they only change the amount of damage and knockback a move does, certain sweet spots can change the properties of the attack, such as turning 's into a meteor smash.
