A misty vapor arises around the character. It is stationary
once created. The vapor obscures all sight, including darkvision,
beyond 5 feet. A creature 5 feet away has one-half concealment
(attacks have a 20% miss chance). Creatures farther away have
total concealment (50% miss chance, and the attacker cannot use
sight to locate the target).
A moderate wind (11+ mph), such as from the gust of wind
spell, disperses the fog in 4 rounds. A strong wind (21+ mph)
disperses the fog in 1 round. A fireball, flame strike, or
similar spell burns away the fog in the explosive or fiery
spells area. A wall of fire burns away the fog in the area
into which it deals damage.
This spell does not function underwater.
