The Witch & The 66 Mushrooms - Getting Slate Early

I haven't tested this in an actual run so I don't know if having the upgraded scythe actually changes anything, but I'm pretty sure this should would. When you shoot three knives, you jump back giving you a slight vertical bump. The scythe also gives you a slight vertical bump. Both of those are needed to get up to where the slate is. I'm pretty sure this is the only jump that requires that much height however I could be missing something. Anyway, this saves like a minute.
