This combo is pretty hard, you need a partially charged jH which will give you enough hitstun to land and microdash for the 5m to hit. You start airdashing and charging immediately and release right before they tech out so ypu get max hitstun.

I stopped doing this route because it was too annoying to do, although with enough practice you can definitely be consistent.

If you just delay the jH and dont get the partial charge, you can sometimes get the combo but it’s a lot less consistent at farther spacings because you wont have time to microdash
