Chaotic Explosion

You hurl an undulating, warbling mote of chaotic energy at a point you can see within range. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving through. A target takes 2d8 + 5d6 damage. Choose one of the d8s. The number rolled on that die determines the attack's damage type as shown below.

d8 | Damage Type
------|------------------
1 | Acid
2 | Cold
3 | Fire
4 | Force
5 | Lightening
6 | Poison
7 | Psychic
8 | Thunder

If you roll the same number on both d8s, the chaotic energy coalesces in the form of a Chaos Bolt and leaps to a single target, the target must have either succeeded on the original saving throw or was not in the original radius. Make a new attack roll at Chaos Bolt's lowest level with a new damage roll.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
