Drawmij's Marvelous Shield

This spell is an improved version of the 1st-level shield spell. The marvelous shield will protect the caster against attacks from all sides, including the rear and above, provided the wizard is aware of the attack. A surprise attack will completely dispel the protection of the marvelous shield. The protection afforded by the spell is an increase of 2 against all attacks, so the improved shield acts as AC 0 against hand-hurled missiles, AC 1 against device propelled missiles, and an Armor Class of 2 against all other attack forms.
