Bahamut's Judgement

An Aspect of Bahamut heeds your judgement, a spectral dragon head appears before you and a blast of blazing white fire erupts from its maw. Each creature in a 60-foot cone must make a Constitution saving throw. A creature takes 10d10 fire damage on a failed save, or half as much damage on a successful one. Any creature with an evil alignment will automatically fail. 

Any creature who dies from this spell will be disintegrated into ash. All material items, apart from those of a magical nature, on its person will be destroyed.
