Cone of Flames

A roaring sheet of blue and white flames bursts from your palm in a 60 foot cone. Creatures in the area of the cone must succeed on a Dexterity saving throw or take 10d6 fire damage, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d6 for each slot level above 5th.
