Chaos Storm

Chaotic energy pounds the ground in a 20-foot radius, 40-foot high cylinder centered on a point within range. Each creature in the cylinder must make a Dexterity saving throw, taking 2d8 + 6d6 damage on a failed save, or half as much damage on a successful one. Choose one of the d8s. The number rolled on that die determines the storms damage type, as shown below.

If you roll the same number on both d8s, the cylinder moves up to 60 feet in a direction of your choice. Make a new damage roll, and apply the results to any creatures caught in the new area of the cylinder, which can cause the cylinder to move again. A creature can be targeted only once per casting of this spell.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d6 for each slot level above 5th.
