Source Pathfinder #2.
The haunted character must make a DC 16 Will save. If he fails, he is compelled to hurl himself through the unbroken window, taking 2d6 points of damage from the shattering glass and a further 1d6 points of damage from the fall onto the rooftop below. A weather vane on the roof makes a single +8 attack against the falling character; if it hits, the character takes another 1d6+7 points of damage, but his fall ends. If it fails to hit him, the character must make a DC 15 Reflex save. If that fails, he slides off the steep roof over the course of one round, whereupon he may make a final DC 10 Climb check to catch himself before falling 300 feet to the rocky surf below, taking 20d6 points of damage in the process.
