Can the knock back granted by open hands flurry of blows be used to push the target vertically?

Pushing someone away requires the whole move to be away from you. A diagonal push works. Vertical doesn't. #DnD https://t.co/5l2tNgKAPH

@JeremyECrawford @Vo1kain vertical is away but most dnd games kinda ignore it for simplicity. I'd rule sure you can push up if you're prone

@ShadowRadiance @Vo1kain Vertical is only away if the creature is on top of you.

If your target is above you, however, you can push them vertically. The point is this: you must push away. #DnD https://t.co/UIqy6WYDTU
