Ok just get deku Sticks and the go find a gossip stone near a ledge. Get close to the ledge and try to hit the gossip stone with the deku stick. You should bounce off and hang on the edge with a broken deku stick in hand. Now you have an Unbreakable Deku Stick that is twice as strong as the Kokiri Sword! And you can also light it. But unfortunatley as soon as you leave the perimeter (where the screen turns black then goes to the next place), it will dissappear and you'll have to do it again.
