Shield

Casters Magic-User 1
Range self
Duration 5 rounds+1/level

Shield creates an invisible, shield-like mobile disk of force that hovers in front of the caster. It negates magic missile attacks directed at the caster, and improves the caster's Armor Class by +3 vs. melee attacks and +6 vs. missile weapons. The Armor Class benefits do not apply to attacks originating from behind the caster, but magic missiles are warded off from all directions.
