Taser

You point your finger at a creature you can see within range, and a thin beam of lightning rushes to your target.  Make a ranged spell sttack against the creature.  On a hit, it takes 6d6 lightning damage and falls prone.  If the target is resistant or immune to lightning damage, it doesn't fall prone on a hit.

At Higher Levels.  When you cast this spell using a 3rd level spell slot or higher, the damage increases by 2d6 for each level above 2nd, up to a maximum of 12d6.
