Blazing Wrath

A stream of fire emanates from you in a 10 foot radius sphere. Each creature in the area other than you must succeed on a Dexterity saving throw or be covered in flames for the spell’s duration or until a creature uses its action to make a Dexterity check against your spell save DC to extinguish the flames on itself or another creature. A creature covered in the flames takes 1d4 fire damage at start of each of its turns, and 2d4 extra fire damage every time it's hit with an attack.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the initial damage increases by 1d4 for each slot level above 1st.
