>**Casting Time:** Action > **Range:** 120 feet > **Components:** V, S > **Duration:** [[Concentration]], up to 10 minutes You create a 20-foot-radius [[Sphere]] of yellow-green fog centered on a point within range. The fog lasts for the duration or until strong wind (such as the one created by Gust of Wind) disperses it, ending the spell. Its area is [[Heavily Obscured]]. Each creature in the [[Sphere]] makes a CON saving throw, taking 5d8 Poison damage on a failed save or half as much damage on a successful one. A creature must also make this save when the [[Sphere]] moves into its space and when it enters the [[Sphere]] or ends its turn there. A creature makes this save only once per turn. The [[Sphere]] moves 10 feet away from you at the start of each of your turns. **Using a Higher-Level Spell Slot.** The damage increases by 1d8 for each spell slot level above 5. **Classes:** #Sorcerer, #Wizard
