Bestial Sling

You quickly fling several sharp rock shards in a line 10 feet long and 5 feet wide. Each creature in the line must make a Dexterity saving throw, taking 2d6 piercing damage on a failed save and half as much on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
