Arc Flight

You rise vertically and radiate arcs of lightning. You gain a fly speed of 30 feet, you cannot use this movement speed to move further than 15 feet from the ground or another solid surface. You can ascend sheer surfaces or even along ceilings in this way as long as you move no further than 15 from a solid surface at any time.

Any creature that makes an opportunity attack against you during the duration of this spell takes 1d6 lightning damage.

When the spell ends, you plummet to the ground if you are still aloft and you take falling damage as normal.
