Thorn bolt

You create a lance of hardened wood and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 2d8 piercing damage and is restrained. A creature that is restrained can use its action to make a Strength check against your spell save DC. On a success, it frees itself.

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.
