Ashe's Lightning Step

You briefly turn into a bolt of lighting and instantaneously teleport up to 60 feet the to an unoccupied space that you can see. This lightning bolt forms a line up to the distance you teleported long and 5 feet wide.Each creature in the line must make a Dexterity saving throw. A creature takes 5d6 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.

You can bring along objects as long as their weight doesn’t exceed what you can carry. You can also teleport one willing creature of your size or smaller who is carrying gear up to its carrying capacity. The creature must be within 5 feet of you when you cast this spell, and there must be an unoccupied space within 5 feet of your destination space for the creature to appear in; otherwise, the creature is left behind.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
