Description
You unleash a storm of flashing light and raging thunder in a 10-foot-radius, 40-foot-high Cylinder centered on a point you can see within range. While in this area, creatures have the Blinded and Deafened conditions, and they can't cast spells with the Verbal component.
When the storm appears, each creature in it makes a Constitution saving throw, taking 2d10 Radiant damage and 2d10 Thunder damage on a failed save of half as much damage on a successful one. A creature also makes this save when it enters the spell's area for the first time on a turn or ends its turn there. A creature makes this save only once per turn.
Using a Higher-Level Spell Slot. The Radiant and Thunder damage increase by 1d10 for each spell slot level above 5.
