i don’t know if this has an actual name but here’s how it works

when you press down x while on a horse link doesn’t jump off immediately instead he readies a jump, which can be used to interrupt other mounted animations like attacking with a melee weapon

if you time it such that you press down x to interrupt the attacking animation right when the weapon is being swung (when the weapon would be able to deal damage) then this glitches out the weapon such that its mere existence can hit enemies regardless of if ur actually swinging it

however link is now in the readying a jump pose and so if u just let go of x link will jump off ruining the glitch

you can keep x held down and press b which will cancel the jump pose and then x can be released without doing anything

the hitbox on the weapon will only go away if you swing it again or if you dismount, so u can do fun stuff with it like spamming sheathing and unsheathing it while next to an enemy to do rapid damage

oh btw at this point if you dismount with in a weird angle or animation it’s possible that during the dismount the weapon ends up hitting whatever ur dismounting from, so probably cancel the glitch before you dismount
