Use the arete on the left side. There's a big hold at the top for the topout. A nice search for the footwork while you're on your way to top this problem.
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
