Create or Destroy Air

You do one of the following:

Create Gas. You create up to 10 gallons of any gas within range in a container, extinguishing or flaring up exposed flames there depending on the gas. During combat, the gas must contain enough air for any creature to breathe in it.

Destroy Gas. You destroy up to 10 gallons of gas in a container within range. Alternatively, you destroy fog in a 30-foot Cube within range.

Using a Higher-Level Spell Slot. You create or destroy 10 additional gallons of gas, or the size of the Cube increases by 5 feet, for each spell slot level above 1.

If a Creature is Inside the Area of the Spell;the creature becomes deafened due to the change in pressure, and the creature must succeed a DC STR save equal to the distance its going to move, in order to not move away or toward (when destroying and creating gas respectively) the center of the spell's area. Flying/airborne creatures automatically fail this check.
