This problem is located on the same block as Le Papillon and shares the start holds. It’s a pretty physical boulder with a surprisingly tricky top-out.
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.
