Agron’s Lightning Dash

You turn into a streak of lightning as you teleport to a spot in range you can see. Every creature you pass through must make a Dexterity saving throw. A creature takes 2d8 lightning damage of a failed save, or half as much on a successful one.

At Higher Levels:  When you cast the spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for every spell slot level above 2nd.
