You cause a 10 foot long, 10 feet tall, several inch thick wall of earth to erupt on the ground, granting total cover and blocking any damage that originates from the far side of the wall until the wall breaks. This blocks ranged attacks, and areas of effects that have a point of origin on the far side of the wall (for example, the center point of a radius spell or the source of a cone or line). All damage the wall blocks is applied to the wall, even if that damage normally only affects creatures, but it takes the blocked damage only once, even if blocking the same damage against multiple creatures. The wall has 4d10 + your spellcasting modifier hit points, and crumbles to dust when it is reduced to 0 hit points. Any damage remaining after the wall is destroyed is dealt as normal. If the wall is not destroyed, it crumbles at the start of your next turn.
