As protection from evil, except that it encompasses a much larger area and its duration is longer.

Unlike protection from evil, this spell has a special function that the character may choose when casting the spell. A magic circle can be focused inward rather than outward. In this case, it serves as an immobile, temporary magical prison for a summoned creature. The creature cannot cross the circle’s boundaries.

The character must beat a creature’s SR in order to keep it at bay (as in the third function of protection from evil), but the deflection and resistance bonuses and the protection from mental control apply regardless of enemies’ SR.

If a creature too large to fit into the spell’s area is the subject of the spell, the spell acts as a normal protection from evil spell for that creature only.

This spell is not cumulative with protection from evil and vice versa.
