Bestows immunity to toxic gas
Unlike Ioun Stone Iridescent Spindle, Ioun Stone Iridescent Sphere does not negate the need to breathe and is effectively useless underwater.
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.
