Ashen Retch

 You conjure a burning cloud of ash that spread out in a 20-foot cone. 

Any creature within this cone must make a Constitution Saving Throw. A creature takes 2d6 fire damage on a failed save and becomes poisoned for 1 minute, or takes half as much damage on a successful save.

At the start of each of their turns they must make a Constitution Saving Throw to overcome the poisoned condition.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
