Aetheric Beam

A massive beam of condensed Aetheric Energy forms a 100 foot long by 5 foot wide line that blasts out from you in a direction you choose. Each creature in the line must make a Dexterity Saving Throw or take 8d6 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 4th or higher, the damage increases by 1d6 for each level above 3rd.
