The globe of protection of this spell is identical in all respects to a protection from evil spell, except that it encompasses a much larger area and its duration is greater. The effect is centered on and moves with the creature touched.
Any protected creature within the circle can break the warding against enchanted or summoned monsters by meleeing them. If a creature too large to fit into the area of effect is the recipient of the spell, the spell acts as a normal protection from evil spell for that creature only.
To complete this spell, the caster must trace a circle 20 feet in diameter using powdered silver. The material component for the reverse is powdered iron.
