Black Fire (H)

You throw a ball of black fire up to 30 feet away. When it reaches the end of its trajectory, the ball detonates. Each creature in a 5-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 1d12 necrotic damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 2nd or higher, the damage increases by 1d12 for each slot level above 1st.
