Conjure Air

This spell allows you to conjure various gasses, some helpful, others toxic, others merely pleasant.
As for all conjuration spells, you may not conjure any substance your character would not be familiar with, and conjured substances aren’t valid components for spells. You may conjure fresh air. You may conjure smoke or even harsh mine gasses. But this doesn't let you conjure pure gasses such as helium or flourine that you would not have heard of, nor does it allow you to conjure modern chemical weapons.
The air conjured will come out of your lungs, though you are not affected unless you choose to be.

Cantrip

You conjure a puff of air near against a target in the zone, as a touch attack. Choose from one of the types below:

• Fresh Air: This is typical air, clean and breathable.
• Dephlogisticated Air: This air has less phlogiston in it making it much easier to breathe than regular air although also doubling all fire damage done to targets within it and otherwise doing anything pure oxygen would do.
• Smoke: Anyone trying to see through this smoke acts as if blinded unless they have supernatural senses.
• Burning Smoke: This acts as smoke, but also blinds anyone who had their eyes open as it hit their face.
• Toxic Fumes: This deals poison damage equal to your Magic Power to anyone who breathes it.
• Acidic Cloud: This deals acid damage equal to your Magic Power to anyone who touches it.
• Firedamp: This highly flammable gas will explode into flames if lit, dealing fire damage equal to your Magic Power.
• Scented Air: This produces any scent you want. Pleasant scents might put a creature in a positive frame of mind and give you an advantage on social rolls while unpleasant scents might cause a creature to flee or puke if their life is not in danger.

Great

Superior

This fills every zone in range as per the cantrip version

Ultimate

This fills everything in range permanently with a type of air from the cantrip version. If it is depleted or blown away, it will quickly refill. This can create a bubble of breathable air in an underwater home, or fill an entire castle with toxic fumes.
