I go over how to use Palutena's Warp (Up B) and using Ledge Cancelling in order to move around the stage and use attacks quickly.
Ledge Cancelling is a known technique where you can cancel the landing animation of a move near the edge of a ledge to be able to move immediately afterwards.
I didn't see any other guides for this techique so I figured I would make something to help Palutena players!
