    "The vehicle's driver can activate this magical device as a bonus action, causing the vehicle to expel a 30-foot cube of opaque smoke directly in front of it or behind it. The cloud is stationary and lasts for 1 minute. The area within it is heavily obscured. Any creature that enters the cloud for the first time on a turn or starts its turn there takes 21 ({@damage 6d6}) necrotic damage. A strong wind disperses the cloud. This device needs 24 hours to recharge before it can be used again."
