The sorcerer places a piece of stone on the ground and
smashes a piece of glass upon it. He then lifts the rock and crushes any
remaining glass fragments with it. After reciting the appropriate incantation,
the caster touches the stone he wishes to transmute. An area within a four
meter radius of his hand then becomes brittle, its Toughness decreased
by the effect total of the spell. The spell has a divination component that
allows it to separate each component piece of rock in a wall, so the effect is
applied against one piece of the wall instead of the wall as a whole. A brick
has a Toughness of 4, a brick sized piece of granite has a Toughness of
9, while a one meter by one meter by half a meter granite slab would have a Toughness
of 24.
