Using X-ray vision is physically exhausting, causing you 1 point of bio-energy drain per minute after the first 5 minutes of use in a single day. Unlike most other xenotheric abilities, X-ray vision can be sustained even after all points of bio-energy are drained, instead inflicting 1 point of Constitution drain for every minute of usage after your bio-energy pool runs out.
