enhanced flame Arrow

A flaming teal arrow streaks toward a target within range and bursts in a teal explosion. Make a ranged spell attack against the target. On a hit, the target takes 6d12 fire damage immediately and 3d6 fire damage at the end of its next turn. On a miss, the arrow burns the target with fire for quarter as much of the initial damage and 1d4 fire damage at the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage (both initial and later) increases by 2d10 for each slot level above 4th.
