If you're struggling with Crimson Desert's double jump as much as I was, it's because of this mistranslation

One of my major complaints with Crimson Desert has been the fact that the double jump and the glide abilities are both bound to the same button if you’re playing on controller. In the nearly two dozen hours I’ve spent futzing with the game, this has been a constant source of consternation—I glide when I mean to double jump, I double jump when I mean to glide.

I thought this was just a case of a crowded control scheme, maybe even something Pearl Abyss would patch out in future updates. As it turns out, I’d just completely misunderstood what the double jump ability did. I can hardly be blamed, though, because the English tooltip really isn’t great at communicating this to you.
