Casting time: 1 Action
Range: 90 feet
Components: V, S
Duration: Concentration, up to 10 minutes
You set up a wall of rotating magic blades. The wall appears at a location you specify within the casting distance and continues until the spell duration ends.
You can choose to create a straight wall that is 100 feet long, 20 feet high, and 5 feet thick; or a circular wall that is 60 feet in diameter, 20 feet high, and 5 feet thick.
The wall provides three quarters of cover for creatures behind it. The space occupied by the wall is considered difficult terrain.
Any creature entering the wall area for the first time in a round, or starting its turn in the area, must make an agility save.
Those who fail the save will take 6d10 points of slash damage. If the save is successful, the damage is halved.
