Okay. Sounds similar but opposite to a semblance I made, which was the ability to control how much oxygen was in a pocket of air. She couldn't remove the oxygen entirely, but she could give anyone who enters it altitude sickness, and cause massive fireballs with a tiny bit of fire dust by overloading how much oxygen the fire has access to.
