Arcane Beam

You blast a glowing beam of magical force that is 60 feet long and 5 feet wide. Each creature in the line must make a Dexterity saving throw. A creature takes 2d6 force damage on a failed save, or 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 spell deals an extra 2d6 and its range extends by 10 feet for each slot level above 1st.
