See Through Fog (3.5e Spell)

Spellcaster, what do your magic eyes see?

You see through any gaseous or fluid medium as if it were only a vague outline, allowing you to see through gas, smoke, and water as if it were clear air. In addition, you automatically identify any magically augmented clouds (such as by control weather), as well as any effects of said clouds (such as the deadly effects of cloudkill.)

Material Component: An ointment for the eyes that costs 250 gp and is made from ash, bat blood, and fat.
