But then they can just firestall forever
Responding to your post from almost a year ago because I might have found a counter to firestalling.
To put this in perspective, let me first give you an analysis of Fox’s firestall.
Amount of intangibility left after
CliffWait 0 (the last frame of ledgegrab lag):
29 frames.
Disabled regrab period: 29 frames, starting to count as soon as you drop from the ledge.
⇒ To stay continuously intangible, it’s absolutely necessary for Fox to drop from the ledge after
CliffWait 0 (and before
CliffWait 1). The amount of frames he waits in
CliffWait is also the minimum amount of vulnerable frames before his ledge regrab. So if he drops after
CliffWait 4 and does the rest of the firestall perfectly, he will be vulnerable for 4 frames before he grabs the ledge again.
Up-B (Firefox) falling start: frame 16 (
308 16 ). On frames 1-15, Fox stays at the same height, so he can never grab the ledge during these frames. On frame 16, he starts to fall down.
Up-B (Firefox) hitbox active: from frame
20 on.
⇒ If Fox lets go of the ledge after
CliffWait 0 and immediately starts his up-B, he grabs the ledge again after frame 29 of his up-B. Because he starts falling as early as after frame 15, he can also waste up to 14 frames doing whatever he wants after the ledgedrop and before his up-B, as long as his ledgegrab box overlaps with the ledge again by the time his up-B starts.
One way to use up these leniency frames is to do a shine-firestall. This has the advantage of getting another hitbox out and delaying the frame where Fox needs to decide his direction.
He can also fastfall for a few frames, shine down there, jump back up within these 14 frames. I will add animations of the very extremes he can go later.
To go back from Fox to Marth,I'm pretty sure that there is no one way that defeats all of Fox's firestall variations. But I did find a tool that defeats some of them: Counter.
If Fox opts for the ledgedrop -> instant Firefox ledgestall, with less than two frames of falling between ledgedrop and up-B, his frame 20 hitbox will be high enough to activate your Counter if you stand directly above him. Your Counter hitboxes also reach down far enough to hit him.
During Counter's pseudo-hitlag, the intangibility timer keeps running, so Fox runs out of his intangiblility frames before your hitbox comes out.
Thus, a firestall that would have been continuously intangible loses this continuity due to the Counter hit.
It is also possible to run off and go for an off-stage Counter to catch lower firestalls as well, but I heavily doubt that it's worth the risk of getting shined. Also, even if you get the hit, Fox can easily walljumptech it and shine you afterwards.
Does anyone remember if there was a post explaining how hitting spacies out of their side-Bs works? I think Kadano posted one, but I can't remember or find it.
In the OP of this thread, under Fox > Hitting out of side-B, I cover low attempts. I wrote some posts about high side-Bs starting here:
