Dimension Drift

The caster releases a white ray of spectral magic originating from a 5-foot-wide, 120-foot-long line. Each creature in the line must make a Dexterity saving throw, taking 10d4 bludgeoning damage on a failed save, or half as much on a successful one.

You can create a new line as your action on any turn until the spell ends.

At the DM's discretion, this can deal aether damage instead.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 2d4 for each slot level above 6th
