There's a specific distance you can stand away from an attacking heavy knight that will cause them to miss you with their attack but still move to the other side of you.

This would probably be most useful on City 1 since it has quite a few heavy guards in awkward places.

After trying it some more turns out it will also work if you just hold down after starting the slide. Makes it a bit easier to do.

Just tried it out and it seems like it happens if you hit down and jump at the same time during a slide.
