Start standing on the left arete with a small crimp for the left hand and a crisp sidepull for the right. Slippery feldspar crystals exist for your feet. Pull up and make a long reach to a sharp three finger pocket on the overhanging wave. Then make a desperate move with your right hand to a deeper pocket above. From here, make a long move up and around the arete to a sidepull, and top out with an exciting mantle.
