A beam of crackling, blue energy lances out toward a creature within range, leaving slivers of static electricity. Make a ranged spell attack against that creature. On a hit, the target takes 2d6 lightning damage, and on each of your turns for the duration, you can use your bonus action to deal 2d6 lightning damage to the target automatically. If the creature leaves your range, you must move back into range to continue using your bonus action to attack.

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