Wave of Oblivion

You create a 30-foot @variantrule[Cone [Area of Effect]|XPHB|Cone] of oblivion. Each @variantrule[Bloodied|XPHB] creature in the @variantrule[Cone [Area of Effect]|XPHB|Cone] makes a Constitution saving throw. On a failed save a creature dies, and it and everything nonmagical it is wearing and carrying are turned to dust. The target can be revived only by a @spell[True Resurrection|XPHB] or a @spell[Wish|XPHB] spell.
