Wall of Light

You conjure an immense manifestation of destructive light side Force 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 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, it must make a Dexterity saving throw. On a failed save, the creature takes 6d10 force damage, or half as much on a success.
