Armor of Elemental Air - Elemental Armor

You create a thin film of permanently fresh air around a target. The target has 5 temporary hit points, and if the target doesn't keep the hit points, the rest of the spell still works. The air allows a air-breathing creature to breathe underwater and without air at all.

Armor of Elemental Air, Armor of Elemental Fire, Armor of Elemental Earth, Armor of Elemental Water, and Armor of Elemental Ice are one spell for the purpose of preparing, called Elemental Armor.  I apologize for not making them a single spell from the beginning.
