Arte's Lightning Dash

You transform yourself into a bolt of lightning and teleport up to 60 feet to an unoccupied space you can see. Each creature in the 5 feet wide line must make a Dexterity saving throw. A creature takes 4d6 lightning damage on a failed save, or half as much damage on a successful one.

The lightning ignites flammable objects in the area that aren’t being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot above 4th. In addition, you can teleport yourself an additional 10 feet further for each slot level above 4th.
