Initiation Time: 1 action
Range: 120 feet
Duration: Concentration, up to 1 minute
You create a wall of flames on a solid surface 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.
When the wall appears, each creature within its area must make a Dexterity saving throw. On a failed save, a creature takes 5d8 fire damage, or half as much damage on a successful save.
A creature takes the same damage when it enters the wall for the first time on a turn or ends its turn there.
At Higher Levels. When you initiate this form at a higher level, the damage increases by 1d8 for every level above 4th.
