A bank of fog billows out from the point the character
designates. The fog obscures all sight, including darkvision,
beyond 5 feet. A creature within 5 feet has one-half concealment
(attacks suffer a 20% miss chance). Creatures farther away have
total concealment (50% miss chance, and the attacker cant
use sight to locate the target).
A moderate wind (11+ mph) disperses the fog in 4 rounds; a
strong wind (21+ mph) disperses the fog in 1 round.
The spell does not function underwater.
