Earthen Wall

You cause the ground to raise at a point you can see in front of you. This ground creates full cover for anyone in front of it. The wall can be broken with an DC 13 Strength Check and is 5ft tall, 5ft Wide. If it is created below a creature of Medium or Smaller size, that creature must make a Dexterity Saving Throw or take 2d4 Bludgeoning damage, is pushed back 15ft, and is knocked prone. If they succeed, they take 1d4 Bludgeoning damage and pushed back 5ft.

At Higher Levels: For each 2 levels upcasted, the one more wall can be created and can deal 1d4 extra Bludgeoning damage.
