Waxen Emberstorm

You conjure a swirling storm of waxen embers, creating an area of chaotic fire.

Effect:

• The area becomes heavily obscured, and any creature that starts its turn or enters the area must make a Constitution saving throw or take 6d6 fire damage. Additionally,  the lungs creatures in the area who failed the saving throw are invaded by magical wax, giving them disadvantage on Constitution saving throws until they leave the area.

At Higher Levels: When cast using a 5th-level spell slot or higher, the damage increases by 2d6 for each slot level above 4th.
