Yeah everything is very barebones at the moment I'm trying to figure everything out but I'm riding a bit solo at the moment LMAO. Sword climbing is a glitch that allows you to basically fly over everything if you have the sword throw and jump attack abilities unlocked and I will post a run of me using the tech as soon as I can, for now though I can do my best to explain it in text form as well as add a little clip of me hitting the tech. You basically just jump and mash both your sword throw button as well as your attack button at the same time. There's a certain rhythm to it and I find it impossible to do on mouse so I would recommend rebinding 2 of your keyboard buttons next to one another to make the mashing a bit easier!
