What is a hyperjump?

See here for some gifs.

How to:

To perform it, start by holding the analog stick diagonally forward and down to run. Next, hit the dodge button. This will start a dodge slide, which you can immediately cancel by jumping. Keep holding forward and you’ll retain your speed boost for a distance. It’s important to hold the stick diagonally forward and down at the start. Holding just forward, you’ll enter a regular dodge rather than a slide. You can still jump out of a regular dodge of course, but dodge slides are faster and give you more distance.

Note:

Keep in mind that Super Jumps are a form of dodge cancelling - this means that your dodge cooldown starts from the moment you jump. All dodge cancels leave you vulnerable, unable to catch arrows for a short time, gaining you mobility in return.
