Invulnerability to Magical Weapons (Abjuration)
Level: Bard 6, Mage 6, Sorcerer 6
Range: Self
Duration: 1 round every 3 levels
Casting Time: 1 round
Area of Effect: 1 creature
Saving Throw: none

This spell creates an immobile, faintly shimmering magical sphere around the caster that cannot be penetrated by magical blunt, edged, or missile weapons; all such weapons are harmlessly deflected (missile weapons strike the sphere, then immediately fall to the ground). However, the sphere offers no protection against creatures whose attacks are magically based (such as the gaze of a medusa). The sphere offers no protection against spells such as magic missile, or spells that simulate the effects of weapons (such as a Flame Arrow spell), but protects against spells that create magical weapons (such as a Mordenkainen's Sword). 

The caster can use magical weapons from inside the sphere to attack opponents normally. Spells can also be cast through the sphere. The sphere can be negated by a dispel magic or any similar spells. This spell will both remove and negate the effects of a Invulnerability from Normal Weapons spell. This effect lasts for the duration of the spell or until dispelled.
