Create or Destroy Air

You either create or destroy air.

Create Air. You create a 30-foot cube of breathable air centered on a point of your choice. Any poisonous gasses in the area are forcibly pushed out.

Destroy Air. You destroy any air in a 30-foot cube within range, removing poisonous gasses or extinguishing exposed flames in the area. Surrounding air will move in to fill the void left, so any creatures within the area will not suffocate. If there is no air to fill the void any creatures within the area will suffocate.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the size of the cube increases by 5 feet, for each slot level above 1st.
