Blinding Wall

You conjure a wall of radiant energy that pulses with blinding light. The wall itself is intangible but tests the wills of those who wish to pass through it. You can summon either a 30 ft. wall or a 15 ft. radius sphere with the blinding daylight focused on one side of the wall that you designate. Creatures within 40 ft. of the wall in its light that can see it must make a Constitution saving throw when the wall is summoned and whenever they look at the wall. On a failed save, the creature becomes blinded for 1 minute. Creatures that make this saving throw must either look away from the wall or else cover their eyes (blinding them) while facing the wall. Creatures attempting to pass through the wall must succeed at a Wisdom saving throw or else take 3d4 radiant damage and 3d4 psychic damage.
