Weirdshield

This spell creates a shimmering, translucent magical barrier that appears at a location of the casters choosing, floating in midair, out to a range of 30 feet. It is shaped like a triangular shield, point down, fringed with many tentacles that end in human-like hands.

This ghostly shield can be moved about by the casters will, moving up to 25 feet per round.

The Weirdshield irresistibly attracts any magically-conjured bladed weapons (such as a Mordenkainen's Sword or Blade of Doom) within 60 feet of it, and negates them on contact (which occurs 1 round after the shield is formed within range of such conjured blades, or they come within its range). It also irresistibly attracts any Dancing Swords within the same range and at the same rate, causing them to fall lifeless to the ground, temporarily becoming +1 weapons under no beings control.

If the shield is within 20 feet of the caster, it automatically intercepts any magical attacks of 4th level and lower that are directed at the caster, and reflects them back at their sources. 

The shield can make an infinite number of such interceptions per round and is itself only destroyed by a Dispel Magic directed at it, the death of the caster, loss of concentration of the caster, contact with a magical barrier of 5th level or lower ( the shield and the barrier destroy each other with spectacular lights and sounds of discharging), or specifically put out of existence by a Wish spell.
