After you get the Scorpion Sword, return to the central room. Turn the turnstile so that the lever is facing the doorway with the save point fountain. Stand facing the opposite doorway and walk up slightly and to the right. You will find a ledge that is one step lower than the area around you. Walk down and grab on to it, then jump to the opposite ledge and jump back and forth to slowly make your way down. Once you reach the bottom, drop down to the ledge below it. Wall Run to the next wall and get ready to jump off and back and forth to make your way up. Wall Run again, and when you reach the end wall, jump to slow your descent again. You will eventually grab onto a ledge. Make your way to the doorway that is next to it, but do not enter. Instead, keep going on the rocks until you see the area where sand is falling. Use the Scorpion Sword to break the wall. Break the rack of weapons and pick up the hockey stick. The hockey stick is unbreakable, but if you throw it the weapon will be lost. It has moderate damage and a relatively slow attack rate.
