Trent Tokens
Ioun Stone Iridescent Spindle - 2011 (Gold)
Sustains the character without air. It doesn’t actually allow the character to breathe in a hostile environment–it negates the need to breathe. It can be used underwater to avoid drowning, in water to avoid ingestion of toxic fluids, and on dry land to avoid inhaling toxic gas–though it has no effect on toxins which are absorbed through the skin or injected.
