@JeremyECrawford Gust of Wind says: "It causes protected flames … to dance wildly and has a 50 percent chance to extinguish them." Is that meant to be 50% chance every round that the flame is in the area?

Gust of wind has a 50 percent chance of extinguishing protected flames, such as those of lanterns. Roll whenever such a flame is introduced to the wind. #DnD https://t.co/dkToDLtMIE
