Potion of Fog

When you drink this potion, a billow of thick fog pours from your mouth, duplicating the effect of the Fog Cloud spell (no concentration required) centered on you. The cloud lasts for 1 hour, and it moves with you, remaining centered on you. As an action, you can expel all remaining fog from your stomach, causing it to remain centered on that space for the duration. The fog produces a scent of your choice.
