You create a vertical wall of whirling, razor-sharp blades made of magical energy from a point you can see within range.

The wall appears lasts for the duration. You can make a straight wall up to 100 feet long, 20 feet high, and 10 feet thick, or a ringed wall up to 60 feet in diameter, 20 feet high, and 10 feet thick. The wall provides three-quarters cover to creatures behind it. The area of the wall is difficult terrain and creatures must spend 4 feet of movement for every 1 foot it moves in the area.

When a creature enters the wall's area for the first time on a turn or starts its turn there takes 3d10 slashing damage and 3d10 force damage.

At Higher Level. When you cast this spell using a 7th level spell slot or higher, the force damage increases by 1d10 for each spell slot level above 6th.
