You create a wall of fire on a solid surface you can see within range. You can make the wall up to 60 feet long, 20 feet high, and 1 foot thick, or a ringed wall up to 20 feet in diameter, 20 feet high, and 1 foot thick. The wall is opaque and lasts for the duration.

A creature that enters within or ends its turn within 5 feet of the wall takes 5d8 fire damage. A creature takes an additional 2d8 fire damage if it passes through the wall. When you cast this spell, each creature within its area must make a Dexterity saving throw. On a successful saving throw, a creature only takes half damage when the wall appears.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
