Was fooling around with customs today and felt like tracking Shulk's back slash damages since I note that there's some incomplete data in the OP. This attack has a bajillion different hitboxes and it's annoying. All of this is recorded with Vanilla Shulk. Maybe I'll do the different MArt variants at some point. Meh.
Standard Back Slash(I know a lot of this is already recorded but I figured I'd include it for completion's sake)
From the front:
Ending/Tip/hilt(? It looks like the hilt anyways...):9%
Everywhere else seems to be 10%
From the back:
Ending:13%
Tip/hilt:14%
Downswing/glass/Beam:16%
Leaping Back Slash
From the front:
Ending:8%
Tip:9%
Downswing(hilt):4%
Downswing(blade):6%
Everywhere else seems to be 10%
From the back:
Ending:16%
Tip:14%(I don't get it why it's suddenly lower than the ending hit...)
Downswing(hilt):11%
Downswing(blade):12%
Everywhere else did 16%
Back Slash Charge
From the front
Ending/slide:3%
Downswing(blade?):6%
Seems to be 4% everywhere else, though I might have gotten a 6% tipper once.
From the back
Slide:6%
Ending (fricken pinpoint on this one): 12%,
Tip: 9%
Beam/hilt:11%
Glass:13%
Downswing:15%
And it did 14% two different times and I haven't been able to figure out why. Maybe it's the hilt downswing?
Some notes:
-Glass is the circle where the MArt kanji appear, for those who don't know.
-Downswing is when the blade is vertical right as Shulk is swinging it.
-It's kinda hard to track the downswing on the custom variants, so downswing may only have the one hitbox and the downswing hilt damage may just the hilt damage in general. However, it was the only time Leaping Back Slash did 4/11 damage, so I feel like there is a separate hitbox there.
-Ending is hitting with the tip at pretty much the instant Shulk touches ground.
-I REALLY wish there was more consistency in hitbox damage output. "okay standard backslash does the same amount of damage on the beam, downswing and glass, so on THIS variant we'll make all of them do different damage!" And then on default the ending hit does less than the tip when you hit from the back, but then on both custom variants it does more.
-This move is super weird. I may have made mistakes. Don't hurt me if some of this is a little off pls.
-If this information is already floating around and the OP just hasn't updated it I'll be super sads cause I've been back-slashing Mario for 2 hours...
