5th-level Spell: Stormwall

Sorcery/Whispering (Evocation)

You create a raging thunderstorm and sculpt it into a wall of lightning and lashing rain. The wall appears in any orientation you choose: horizontally, vertically, or diagonally. It can be free floating, or it can rest on a solid surface. You can make the wall up to 80 feet long, 40 feet high, and 5 feet thick, or a ringed wall up to 25 feet in diameter, 40 feet high, and 5 feet thick. The wall is opaque and lasts for the duration.
When the wall appears, each creature within its area must make a Dexterity saving throw. On a failed save, a creature takes 4d12 lightning damage, or half as much damage on a successful save.
No sound can pass through the wall, and creatures within 10 feet of it are deafened. Creatures moving through the wall are buffeted by winds and lashed by lightning. For every 1 foot a creature moves through the wall, it must spend 4 feet of movement. Furthermore, the first time a creature enters the wall on a turn or ends its turn there, the creature must make a Dexterity saving throw. It takes 4d12 lightning damage on a failed save, or half as much damage on a successful one.
As a bonus action on each turn after the first, you may select one creature you can see within 30 feet of the wall or one creature at random within 10 feet of the wall. A lightning bolt leaps out, dealing 2d12 lightning damage, or half as much if the target succeeds on a Dexterity saving throw.
