This spell grants up to ten willing creatures you can see within range the ability to walk on heavily obscuring water vapour (such as cloud, fog, and mist) as if it were solid ground until the spell ends. An affected creature can suspend this effect on itself as a bonus action, allowing it to pass through water vapour until it restarts the effect, which it can do as a bonus action.
A creature affected by this spell falls at a rate of 60 feet per round, takes no falling damage when it lands, and can land on its feet. In addition, its jump distance is quadrupled when it jumps off of water vapour, but it leaves an obvious contrail in its wake.
