Djriixim’s Purple Haze

You create a bank of thick purple vapor that takes up a 20-foot cube within range. Any living creatures caught within the vapor are incapacitated. An affected creature remains incapacitated even after leaving the vapor, but can make a Constitution saving throw to end the effect at the end of each of its turns while not within the vapor.

A moderate wind (at least 10 miles per hour) disperses the cloud after 4 rounds. A strong wind (at least 20 miles per hour) disperses it after 1 round.
