Up to ledge right end of roof, then climb the short flake to clip the fixed hanger on the headwall to the left. Swing out left and claw past a carrot bolt (crux) to a sloping ledge below a bulge and another carrot bolt. Straight up over the bulge for 2m then diagonally left to a small spike/flake. Up left again to enter the large crack then up the wall right of the piton to finish. Alternatively, another good way to finish is as for Gates of Mordor.
