Aura of Chaos

Create a 30ft radius aura of chaos around you. When a creature starts their turn in the aura or when they first enter the aura they gain as many stacks of chaos as you have. At the end of your turn every creature in the aura makes a charisma saving throw, the creature with the lowest result take cold damage equal to their stacks of chaos. The creature that takes the damage removes 2d10 stacks of chaos.
At higher levels: increase the radius by 10ft for each level above 6th
