Wall of Faith

You project a barrier of light around yourself, providing three-quarters cover to creatures you choose within 10 feet of you. This barrier travels with you.

The barrier has Hit Points equal to your maximum Hit Points. Whenever an attack roll is low enough to miss a target within the barrier but high enough that it would have hit the target if there had been no cover, it hits the barrier instead, dealing the damage it would have dealt to the barrier. When the barrier is reduced to 0 Hit Points, this spell ends.

At Higher Levels. When cast with a spell slot of 4th level or higher, the barrier's Hit Points increase by 20 for each level above 3rd.
