AirPouch

You conjure up a magical pouch on the floor within a 5ft range. This pouch is no larger than the size of human head. roughly 60cm in diameter. It is made out of brown leather with drawestrings.

Once conjured, with a bonus action you can magically add oxygen into the pouch which will stay in the pouch if it is open or closed and enough to last for upto 1 hour. With a bonus action you can also remove the Oxygen out of the Pouch.

You can use the pouch to either breath out of by sucking in the oxygen through the entrance of the pouch or by placing the pouch on your head and fastening the drawstrings to keep it on your head. As the pouch is made out of leather it is waterproof but can be damaged with either piercing or slashing damage. If the pouch is damaged this will break the spell and the oxygen will release into the atmospher. for each level you up cast this spell the amount of oxygen and duration increases by an hour.
