In any% right after you exit ZR, you do like a forward sidehop or something to get the WESS. Can anyone explain the entire thing?
The forward sidehop is a result of the weird jumps Link can do after a roll. You have to hold down-left very slightly to do a roll to the left and then you sidehop right to go diagonal. Then you just jumpslash right before hitting the water to recoil off the wall, hold right ESS when you hit the water, and then turn very slightly to angle yourself towards Kakariko. This method is really difficult though.
