Chaos Burst

You hurl an undulating, warbling mass of chaotic energy at one creature in range. All creatures in the area must make a DEX Saving throw. On a failure, the target takes 8d8 damage, half as much on a successful save. Choose one of the d8s. The number rolled on that die determines the attack’s damage type, as shown below.

At Higher Levels. When you cast this spell using a spell slot of 4nd level or higher, each target takes 1d8 extra damage of the type rolled for each slot level above 1st.
