Wavedashing

Jump and immediately air-dodge diagonally into the ground to turn the dodge's momentum into a short ground slide.

Also called: Wave dash, Grounded air dodge

PPMD's Marth varies the distance of repeated wavedashes and follows the slides with forward smashes in Training Mode. Source: PPMD: Melee Movement Practice Guide at 25:45.

How it works

  1. Press jump and wait until your character leaves the ground.
  2. Angle the control stick diagonally down in the direction you want to travel.
  3. Press an air-dodge button before rising far from the ground; a shallower angle produces a longer slide.
Use it when
You want to approach, retreat, or reposition while staying ready for a grounded action.
Watch for
Pressing too early gives a grounded input; pressing too late leaves you air-dodging above the stage. Distance varies by character.
Practice
Practice in both directions on a flat stage with Luigi, then shorten the gap between jump and air dodge.
