Aerial Spear

You hurl a condensed bolt of wind at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 bludgeoning damage and makes a Constitution saving throw. If the target fails they are either knocked prone or pushed back 5 feet (your choice). 

At Higher Levels.  When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
