> **Casting Time:** Action > **Range:** 120 feet > **Components:** V, S, M (a pinch of phosphorus) > **Duration:** [[Concentration]], up to 1 minute 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 a [[Spell Components|Verbal]] component. When the storm appears, each creature in it makes a CON saving throw, taking 2d10 Radiant damage and 2d10 Thunder damage on a failed save or 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. **Classes:** #Warlock, #Wizard
