Thousand Darts 2014

You launch thousands of needlelike darts in a 5-foot‐wide line that is 120 feet long. Each creature in the line takes 6d6 piercing damage, or half as much damage if it makes a successful Dexterity saving throw. The first creature struck by the darts makes the saving throw with disadvantage.

When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
