Weapon of Warding

The focus of this spell flies upward above your head and takes a defensive position within your space. It lunges at opponents, as if guided by a martially trained hand, parrying and turning back melee attacks aimed at you, but does not strike back at any opponent nor does it damage them. The weapon serves only as a defense. While it protects you, you do not provoke attacks of opportunity and have a plus 1 to your AC
