From the Quintino Sella Hut head up the Felik Glacier in a NE direction. Pass pt 3744m to its L and continue ascending slightly, before swinging to the E onto the Glacier de Lys, once above crevassed ground, broadly heading for the foot of il Naso, slanting slightly SE to get to its foot. This may be skinned, but in normal conditions is negotiated at least partly on crampons, with or without the odd ice screw runner if needed. Once over this nose head steeply down and L into a broad easy open snowy bowl underneath the E summit of Lyskamm, 4527m. There now follows about a kilometre of fairly flat glacier heading to the SE. You are aiming for the saddle to the L of Pyramid Vincent. Once closer to this peak you join other tracks from below which you follow and continue skinning easily to the summit at 4215m. Admire the panoramic views, particularly to the S and E. Ski initially down the route you have just came up, curving to the L and then descending to the Gnifetti hut at 3647m.
