The Armor spell allows the wizard to create a magical field that protects as if it were splint mail.
By means of this spell, the wizard creates a magical field of force that serves as if it were scale mail armor (Armor Class: 6). It is cumulative with Dexterity and, in the case of Fighter/Mages, with the shield bonus. The Armor spell does not hinder movement, adds no weight or encumbrance, and does not prevent spellcasting. It lasts until successfully dispelled or until the duration runs out.
