By pushing upward with your hand and speaking in a commanding voice, you cause indentations to form in the surface you designate.

You create a path of handholds and footholds up the surface of a cliff face, tree trunk, wall, or other vertical obstacle. This effect changes the surface to the equivalent of a very rough wall (Climb DC 10).
