The first move of this boulder really packs a punch but pretty cruisy once you're off the ground. Sitstart with the two low diagonal crimps and exit directly.
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.
