The first four hits of Luigi's dash attack use the rapid effect.
The rapid effect (known internally as rush) is used by a small amount of attacks in Super Smash Bros. Ultimate, mainly those that strike quickly and repeatedly. The effect has a subtle aesthetic difference from the normal effect, in that the random displacement of the visuals when hitting an opponent is larger, with a maximum distance of 7 units from the collision point instead of 2 units. Otherwise, both effects function identically.

Trivia
- When an opponent is sent into tumbling by a rapid attack, the launch smoke trail doesn't appear for unknown reasons.
