BOOK I - FARORE'S WIND
Farore's Stall and Other Farore's Ledge Movement
Farore's stalling is something beyond useful that begins the march towards Zelda's insanely sticky ledge presence. If done perfectly you can be completely invuln on ledge indefinitely while throwing hitboxes. The tolerance for this is reasonably tight but not frame perfect. I find the easiest way to accomplish this is using C away / down and up on the control stick. It's also possible to use down control -> Y then up control+B; I find this less reliable as neutral / side B inputs are more likely to happen and are usually fatal. It is most important that you jump within a frame of letting go of ledge as Farore's will snap cancel as soon as the ledge becomes available to you again. Wasting frames in fastfall is what I find most often putting me into a vulnerable state during a stall. This will be a difficult movement to master, experiment with different inputs and see what works for you.
Another useful mixup is ledgehop Farore's. This is valuable as you can adjust the starting height of Farore's stall without losing invuln, and ledgehop Farore's visually appears to be a stall until you crest ledge, land, and teleport across stage. It's a great way to regain stage control when being pressured on ledge from a medium distance.
Many of these options can be combined for maximum flashitude. For example, Battlefield has a ledgehop Farore's edge cancel on top platform. You can drift teleport away from ledge while stalling to throw a farther out hitbox and still magnet ledge. Be creative; the best way to use these techniques is all of the ways.
