Chaos Booolt

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 + 1d6 damage. Choose one of the d8s. The number rolled on that die determines the attacks damage type, as shown below.
d8 / Damage Type
1 / Acid
2 / Cold
3 / Fire
4 / Force
5 / Lightning
6 / Poison
7 / Psychic
8 / Thunder
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 each casting of this spell.
