You create a swirling tunnel of strong wind extending from yourself in a direction you choose. The tunnel is a line 60-foot long and 10-foot wide. The wind blows from you toward the end of the line, which is stationary once created. A creature in the line moving with the wind adds 10 feet to its speed, and ranged weapon attacks fired with the wind don’t suffer disadvantage due to long range. Creatures in the line moving against the wind spend 2 feet of movement for every 1 foot they move, and ranged weapon attacks fired through the line against the wind are made with disadvantage.

The wind tunnel disperses gases and vapors, and it extinguishes candles, torches, and similar unprotected flames in the area. It causes protected flames, such as those of lanterns, to dance wildly and has a 50 percent chance of extinguishing them.
