Chaos Bolt

You hurl an undulating, warbling mass of chaotic energy at one creature in range. Make a ranged spell attack against the target. On a hit, the target takes 2D8 damage. Choose one of the D8s. The number it rolled determines the type of damage, as shown below.

If you roll the same number on both D8s, the chaotic energy leaps from the target to a different creature of your choice within 30 ft of it. Make a new attack roll against the new target, and make a new damage roll, which could cause the chaotic energy to leap again. A creature can be targeted only once by this mass of chaotic energy.

Using a higher-level spell slot: When you cast this spell using a spell slot of 2nd level or higher, each target takes extra damage of the type rolled. The extra damage equals 1D6 for each slot level above 1st.
