Chaos Storm

A storm made up of sheets of roiling chaos appears in a location you choose within range. The area of the storm consists of up to ten 10-foot cubes, which you can arrange as you wish. Each creature in the area must make a Dexterity saving throw. It takes 7d10 + 1d8 damage on a failed save, or half as much damage on a successful one. The damage type is determined by the number rolled on the d8(you roll for each cube separately). The face of each cube must be touching another cube. If more than one cube contain the same roll on the d8 and are adjacent to one another than each creature in one of those cubes must make the saving throw again, if the second rolled number matches the damage type of another cube you may apply this effect to that cube(you cannot effect the same cube more than once).
