# Jallarzi's Storm of Radiance *5th-level, Evocation*  - **Casting time:** 1 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](Mechanics/CLI/rules/variant-rules/cylinder-area-of-effect-xphb.md) centered on a point you can see within range. While in this area, creatures have the [Blinded](Mechanics/CLI/rules/conditions.md#Blinded) and [Deafened](Mechanics/CLI/rules/conditions.md#Deafened) conditions, and they can't cast spells with a 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 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 `d10` for each spell slot level above 5. **Classes**: [Bard](Mechanics/CLI/lists/list-spells-classes-bard.md); [Wizard (Evoker)](Mechanics/CLI/lists/list-spells-classes-evoker-xphb.md "subclass=XPHB;class=XPHB"); [Wizard](Mechanics/CLI/lists/list-spells-classes-wizard.md); [Warlock](Mechanics/CLI/lists/list-spells-classes-warlock.md) *Source: Player's Handbook (2024) p. 289*
