Vacuum Adaptation

The power to hold one’s breathing for an extensive period of time. Not to be confused with Atmospheric Adaptation.

Capability
The user’s lungs evolve rapidly to adjust to the lack of inhaled oxygen so the user can hold their breath for a long time. The body will make its own oxygen as long as it permits before it will shut down if the user can’t get to an oxygen supply.

Low level users can hold up to 2.5 hours, while high level users can go without air for 24 hours plus.

Limits
Can cause seizures after extended use.
