By imbibing this magical liquid, the individual causes his or her body, as well as what it carries and wears, to become gaseous in form and able to flow accordingly at a base speed of 3”/round. 

(A gust of wind spell, or even normal strong air currents, will blow the gaseous form backwards at air speed.) 

The gaseous form is transparent and insubstantial. It wavers and shifts. 

It cannot be harmed except by magical fires or lightnings, in which case damage is normal. 

A whirlwind will inflict double damage upon any creature in gaseous form. 

When in such condition, the individual is able to enter any space which is not airtight, i.e., a small crack or hole, which allows air to penetrate, also allows entry by a creature in gaseous form. 

The entire potion must be consumed to achieve this result, and the effects last the entire duration.
