Great side climb from Refuge de Nice - hiked up to Lac Long, and headed up a steep v-notch to the Brêche de Risso. I had not seen a topo so I followed the grassy ledges to the northeast, then traversed around and to the top of the North Summit, then South across the razor sharp ridge towards the true summit, followed by a couple of 5.6/5.7-ish moves before standing on top of Roche Risso. Downclimbed to the East and retraced the traverse back to the Brêche. 3 hours roundtrip from the Refuge, moving fast. Reading an actual topo would probably help keep the climb at very low class 5…
