OK so
@Youphemism you need to change the universal corner combos section because most of them start with F224 which doesn't exist in Bone Shaper.
Also some of these combos have df2? That doesn't exist in Impostor... So you gotta look into that section.
Anyway, I found these new meterless hitconfirmable corner combos in Bone Shaper, they work on all characters:
B31d2 d1 d1 d1 d1 112 xx BF3 - 25%
F31d2 d1 d1 d1 d1 112 xx BF3 - 27%
4 d1s = total swagness, but a little difficult to pull off. Much easier with 3 d1s and you lose 1% damage.
EDIT: I had to make a video because of how swag this combo looks lol
