Chaos Containment Sphere

The true power of this spell lies in the strength of its barriers, for few other things can withstand the raw fury it unleashes. Make an Arcana check, and multiply the result by ten to get the radius of the spell. A small, shimmering transparent globe forms between your hands, then expands to size as it flies towards the target area. This spell spreads around corners, and automatically damages any part of unattended objects, structures, or magical constructs in its area, though you must have line of sight to the target area when casting. Any creatures in the area of the spell are scoured and pulverized by an explosion of chaotic elemental forces, and must make a Constitution saving throw(living constructs make the save at a disadvantage): on a success they are incapacitated and take spellcasting ability modifier Constitution damage until the end of their next turn; on a fail, the target takes 6d6 fire damage and 6d6 cold damage and 6d6 lightning damage and 6d6 thunder damage and 6d6 radiant damage and 6d6 force damage and spellcasting ability modifier additional damage, and if bloodied by the attack the target takes spellcasting ability modifier Constitution damage until the end of their next turn. Creatures, unattended objects, and structures reduced to 0 hit points by this spell crumble away into fine dust.

If cast above 7th level, for each spell slot expended above level 7 the spell does additional spellcasting ability modifier Constitution damage.
