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.
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 feet 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.
At Higher Levels. 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.
