Flame Staff

You create a staff made of flame and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 bludgeoning damage. Hit or miss, the staff then explodes. The target and each creature within 5 feet of the point where the staff exploded must succeed on a Dexterity saving throw or take 2d6 fire damage.

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