Magical energy has always been used as a powerful weapon. Due to this,
certain spells have been woven that take the opposite magical aura.
Similar to the field spell, anti-magic-field, this spell is able to create
an aura around the target which is able to lessen the amplitude of pure
magic that attempts to penetrate it to attack the target. A result of this,
is a reduction in damage done when these types of attack spells are used.
