Thunderdash

Your body becomes a flash of lightning, teleporting you to a location within 30 feet. Your movement creates a crackling bolt of electricity between your starting point and destination, allowing you to pass through creatures and obstacles unhindered. This movement does not provoke opportunity attacks.

Each creature in a line 5 feet wide between your starting point and destination must make a Dexterity saving throw. On a failed save, a creature takes 2d6 lightning damage, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the lightning damage increases by 1d6 for each slot level above 2nd.
