> **School:** Evocation > **Casting Time:** Action > **Range:** 150 feet > **Components:** V, S > **Duration:** [[Concentration]], up to 1 minute A 20-foot-radius sphere of whirling air springs into existence, centered on a point you choose within range. The sphere remains for the spell's duration. Each creature in the sphere when it appears or that ends its turn there must succeed on a STR saving throw or take 2d6 bludgeoning damage. The sphere's space is difficult terrain. Until the spell ends, you can use a bonus action on each of your turns to cause a bolt of lightning to leap from the center of the sphere toward one creature you choose within 60 feet of the center. Make a ranged spell attack. You have advantage on the attack roll if the target is in the sphere. On a hit, the target takes 4d6 lightning damage. Creatures within 30 feet of the sphere have disadvantage on WIS ([[Perception]]) checks made to listen. **Using a Higher-Level Spell Slot.** When you cast this spell using a spell slot of 5th level or higher, the damage for each of its effects increases by 1d6 for each slot level above 4th. **Classes:** #Sorcerer, #Wizard
