Advuth's Lens Array

Twelve glass lenses you are holding when you cast this spell rise into the air and spin slowly around you. Your AC increases by +2.

If you are in bright light, as a bonus action you may orient the lenses to fire a beam of light at a target you can see within 120ft. They must make a Dexterity saving throw; on a failed save, they take 5d6 radiant damage. On a successful save, they take only half. After one minute, the panes lose their magic and fall to the ground, shattering.
