Wall of Fire

Duration: 1 minute, Concentration
You create a wall of fire, up to 60 ft long, 20 ft
high, and 1 ft thick, or a ringed wall up to 20 ft
in diameter, 20 ft high, and 1 ft thick. When it
appears, creatures in its area make a Dex save.
On a failure, it takes 5d8 fire damage, or half as
much on a success. One side deals 5d8 fire
damage to creatures that end their turn within
10 ft of it or inside it.
At Higher Levels. Each extra spell slot increases
the damage by 1d8.
