A bright spark flashes from your hands and a point you can see within range instantly blossoms with a low roar into a flash of sickening light and devastating force. Select a point within 120 feet, everything in a 10-foot-radius sphere centered on that point must make a Constitution saving throw. A target takes 2d4 radiant damage, 2d4 force damage, and is poisoned on a failed save, or half as much damage and is not poisoned on a successful one. A small mushroom cloud then rises from the location. 

Any creature killed by the light is vaporized and only a shadow in the form of that creature’s last pose remains. Non-magical items the creature is wearing or carrying are also destroyed, but any magical items are left undamaged. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, both damage types increase by 1d4 for each slot level above 1st. When you cast this spell using a spell slot of 3rd level or higher, the radius is of the sphere increases by 5-feet for every two levels above 1st.

For every spell level above 1st used to cast this spell, the area of effect remains toxic for one year. A creature is poisoned for 24 hours for every 6 hours it spends in the area during this time. Each creature also takes 1d4 necrotic damage and 1d4 poison for every 12 hours spent in the area while it is toxic.
