Funny version of the more known Bouddha bloc that you can find on the top of the hill of Isatis. The first move seems far, but if you pull your weight enough on your right foot and lock the left arm you will get to the pocket.
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.
