Synaptic Scorch

Choose an area in range and cause flames to erupt that wreath around the heads of all creatures in the area. Each creature in a 20-foot-radius sphere centered on that point must make a dexterity saving throw. A target takes 8d6 fire damage on a failed save, or half as much damage on a successful one.

On a failed save, a target suffers burning mind for 1 minute. While under the effect, it rolls a d6 and subtracts the number rolled from all its attack rolls and ability checks, including its Constitution saving throws for concentration. The target may make a dexterity saving throw at the end of each of its turns. A success ends this effect.
