Cone of Fire

A blast of white-hot fire erupts from your hands. Each creature in a 60-foot cone must make a Dexterity saving throw. A creature takes 8d8 fire damage on a failed save, or half as much damage on a successful one. If a creature fails the save by 10 or more, the creature catches on fire. At the start of the creature's turn, they take 2d8 fire damage. The creature must use an action to put out the fire. Alternatively, another creature can use their action to put out the fire.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
