The user must be in contact with the surface he wishes to affect to use this technique, as though using Jishin no Jutsu. The Cave-in Crusher is used exclusively to collapse the roof of a cavern or tunnel or cause a landslide on the side of a cliff. Creatures caught under the roof in the area of effect suffer 5d8 point of earth damage and must succeed a Reflex save or be pinned beneath the rubble.
A pinned creature suffers 1d6 point of nonlethal damage per minute, increasing by 1 die every minute (2d6 the second, 3d6 the third and so on). If it falls unconscious, it must make a Constitution check (DC 15) every round or take 1d4 point of damage until freed or dead. If the area does not have a cliff, roof or similar structure, the technique has no effect other than a violent and brief earthquake that will cause creatures to fall prone if they fail a Reflex save (DC 15).
