Smoke and Fire

Smoke obscures visibility, moves around (according to unknown rules), and comes in varying densities.
The formulas at SMOKREF.DAT are very enlightening.
Fire spreads with a speed of one square per turn. A tile on fire will leave a burnt tile after the fire is extinguished. Fire creates smoke. See Incendiary for more details.
