Wall of Faith

You create an impenetrable wall of divine magic. The wall is 1 inch thick, and can be up to 20 ft. wide and 20 ft. high. The wall blocks all movement and attacks from the side facing away from you from where you cast it, but everything from the other side can pass through it without restrain. If a creature attacks the wall with a magical melee weapon you must succeed on a Concentration saving throw as if you had taken damage from the hit, the wall's AC is considered 10 for that attack. A creature of huge or larger can make a shove against your spell save DC, breaking the wall on a success. A Dispel Magic or Disintegrate spell would also destroy the wall.

While concentrating on Wall of Faith you can cast it again using a new spell slot to create one additional Wall of Faith, doing so will also refresh the duration of the spell. You resume to concentrate on the spell as if it were a single spell, but maintaining concentration becomes more difficult. When you do so you cannot cast spells except cantrips, and the Concentration DC is increased by 3 for every Wall of Faith after the first. When one wall breaks, all connected walls break with them.
