You create a wall of magical blades 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 is difficult terrain.
When a creature enters the wall's area for the first time on a turn or starts its turn there, it must make a Dexterity save. On a fail, the creature takes 6d10 slashing damage, or half as much on a success.
