Shield - Great
This shield protects an area. Unlike the other shields, the great shield is immobile and the caster assigns it to a fixed position when he casts it. The size of the great shield can be anywhere from the size of an individual shield up to a plane that is 1 area wide and 3 stories tall. It can be located anywhere within the area of effect, but the caster must see the location to place it. The great shield has an Armor rank equal to the spell rank +2CS. It is usually transparent, but strange runes can be seen scrawled around the edge. If it is struck by an attack with a higher power rank it is shattered and disappears, though no damage penetrates it to harm the caster during that round.
A caster can have only 1 great shield in effect at any time.
This is a magical version of a Force Field.
