Tybji's Chaotic Storm

Chaotic energy pounds the ground from a cloud infused with wild magic in a 40-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 save. Choose one of the d8s. The number rolled on that die determines the storms damage type, as shown below.

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 cloud rumbles and causes another magic surge. Make a new damage roll, and apply the results to any creatures caught in the area of the cylinder again. This effect can happen only once per turn.

As a bonus action on your subsequent turns, you can move the cloud up to 30 feet within range and cause the cloud to erupt in another chaotic storm.

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