Upon activation, the machine spins up a vortex of wind in its barrels and fires it outward in a sixty foot line, with a ten foot width in the direction of your choosing. If a creature begins its turn in the vortex, it must make a STR saving throw, and on a failure, it is knocked 15 feet in the direction of the vortex.   When walking through the Vortex, creatures must use 2 feet of movement for every 1 foot moved, when going against the vortex (towards the user).   The vortex of air disperses any gas or vapor, and extinguishes unprotected flames (i.e. candles, torches, open fires, etc.). Protected flames have a fifty percent chance of being extinguished.   As a bonus action on any successive turns during the duration of the effect, you may change the direction the vortex is blowing in.
