A bank of fog billows out from the point you designate.

The fog obscures all sight, including darkvision, beyond 5 feet.

A creature within 5 feet has concealment (attacks have a 20% miss chance).

Creatures farther away have total concealment (50% miss chance, and the attacker can't 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.
