Prerequisites: 7th-level contractor.
Select one alignment. When the contractor projects her barrier, she can create a magic circle effect against that alignment (as magic circle against evil) with an area equal to that of her barrier. The circle may be focused either inward or outward, as the spell. The contractor cannot augment this circle with a diagram, but there is no actual circle of powdered silver to be disturbed. A creature trapped within an aligned barrier must somehow force the contractor to dismiss her barrier, or simply wait until her barrier rounds run out, in order to escape.
