Sitting start on the right of the block which may be a little stretched if you're super short. (use a thick pad). Fun moves traversing left on slopers and pockets, leads to a hanging foot-jam rest. Don't forget to pad the rock below the top-out, the tiny foot-hold is apt to eject you at the last minute!
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.
