You create a vertical wall of whirling, razor-sharp blades made of magical energy. The wall appears within range and lasts for the duration. You can make a straight wall up to 100 feet long, 20 feet high, and 5 feet thick, or a ringed wall up to 60 feet in diameter, 20 feet high, and 5 feet thick. The wall provides three-quarters cover to creatures behind it, and its space is difficult terrain.

When a creature enters the wall's area for the first time on a turn or starts its turn there, the creature must make a Dexterity saving throw. On a failed save, the creature takes 6d10 slashing damage. On a successful save, the creature takes half as much damage.

You create a wall of whirling blades made of magical energy. The wall appears within range and lasts for the duration. You make a straight wall up to 100 feet long, 20 feet high, and 5 feet thick, or a ringed wall up to 60 feet in diameter, 20 feet high, and 5 feet thick. The wall provides Three-Quarters Cover, and its space is Difficult Terrain.

Any creature in the wall's space makes a Dexterity saving throw, taking 6d10 Force damage on a failed save or half as much damage on a successful one. A creature also makes that save if it enters the wall's space or ends it turn there. A creature makes that save only once per turn.

2024 version from the SRD 5.2. Most tables settle on one edition, so check which one yours uses.
