You create a wall of crackling lightning on a solid surface within range. You can make the wall up to 60 feet long, 20 feet high, and 1 foot thick, or a ringed wall up to 20 feet in diameter, 20 feet high, and 1 foot thick. The wall vanishes when the spell ends.
When the wall appears, each creature in its area must make a constitution saving throw. On a failed save, a creature takes 2d10 lightning damage, and it is stunned for 1 minute. On a successful save, it takes half as much damage and isn’t stunned. This effect also applies to creatures who enter the wall's area for the first time on a turn, and those who end their turn in the wall's area. A stunned creature can make a constitution saving throw at the start of each of its turns, ending the effect on itself on a success. On that turn, they can then move up to their speed, but can't use any actions, bonus actions, or reactions.
Creatures stunned by this spell who end their turn in the wall’s area take 2d10 lightning damage.
At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
