Comet Rush

You imbue a creature that you touch with the speed and power of a flying asteroid. That creature moves up to 30 feet in a straight line, moving through any creature as if it were not there. Each creature caught in the line must succeed on a Strength saving throw or take 2d8 bludgeoning damage, plus 1d8 cold damage, taking half on a success. A creature that fails its saving throw also falls Prone.

At Higher Levels. When you cast this spell using a spell slot of 3rd-level or higher, the cold damage dealt increases by 1d8 per spell slot level above 3rd.
