Create or destroy air

You either create or destroy air.
Create Air
You replace, replenish, and refresh the air in a personal air envelope for 10 minutes for any creature within range,
including air poisoned/tained by spells such as Cloudkill and Stinking Cloud. This does not create a larger in size envelope,
but simply replenishes the air in the envelope that the creature drags with it. If the air is fouled, the air turns fresh
again and the air timer resets to 10 minutes. If used within a spell or effect that causes a cloud (similar to the Fog Cloud,
Cloudkill and Stinking Cloud spells) the creature is allowed an immediate save against the effects of the spell.
Destroy Air
The air envelope of a target creature within range immediately is reduced to Fouled status, with all effects of Fouled status. If air is already Fouled status, this spell has no effect.
At higher levels
When you cast this spell using a spell slot of 2nd level or higher, you may target one additional creature for each slot above 1st
