This glitch makes it so that links sword always registers as swinging, and will also not allow him to walk off edges, perfect for invisible walkways. To preform it, you need to take out your sword (works with any sword) and crouch in front of an interactive object. Don't use a sign that can be chopped or a person, but anything else should work, including bombs. Jab attack it and quickly press A. You want to interact while the sword is extended. If you do it correctly your sword should look like it's slightly glowing. DO NOT SWING. Swinging will cancel the glitch, and you will need to do it again. The swords hitbox will now register as swinging and permanently do damage. If you put the sword away, backflip and press B in midair.
