Clay Barricade

As you grasp the Earth, it erupts before you as protection. A hardened clay wall 15 feet long and 10 feet high and 5 feet thick arises to shield you and your allies. Creatures within the wall when the spell is cast are pushed 5 feet away from the wall into an unoccupied space. The wall has an AC of 18, 40 HP, and is immune to fire damage.

Whenever a creature hits the barricade with a melee attack, you can use your reaction to cause an earthen spike to extend from the barricade and attack the creature. Make a melee spell attack that deals 2d8 piercing damage on hit.

At Higher Levels: When you cast this spell with a slot of 5th or higher, increase the HP of the wall by 10.
