With a calming gesture and soothing word, you calm the air in a 60-foot cube centred on a point within range for the duration. In the area, wind becomes still, the flow of poisonous gases is halted, and the effects of air-based spells of a level equal to or lower than this spell, such as the wind drake spell, are prevented and suppressed.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the level of air-based spells suppressed by this spell increases.
