Conjure a wall of invisible force in an unoccupied space you can see within range. The wall is 5 feet wide, 5 feet tall, and 1/4 inch thick. The wall is transparent, but acts as a physical barrier and can provide cover. It lasts until the spell ends.

The wall has 20 hit points and an AC equal to your Spell Save DC. The spell ends early if the wall drops to 0 hit points.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the wall's hit points increase by an additional 10 points for each slot level above 1st.
