Storm Door

4th-Level Conjuration

Casting Time: 1 action
Range: Self
Components: V, S, M (a piece of fulgurite)
Duration: Concentration, up to 10 minutes

Crackling with lightning, you teleport up to 120 feet to an unoccupied space that you can see. Each creature within 5 feet of both the space you left and your new space must make a Dexterity saving throw. A creature takes 1d12 lightning damage on a failed save or half as much damage on a successful one.

On each of your turns for the duration, you can use your bonus action to call up the lightning and open such a storm door again, targeting a different space with the door each time. If you are outdoors when you cast this spell, a storm develops within 1 minute and follows you, and under such conditions, the spell’s damage increases to 2d12, and you can teleport up to 240 feet.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, a creature of your choice within 5 feet of you can teleport through the storm door with you. Accompanying creatures do not suffer the lightning damage.
