Invocation Grade: Least
Equivalent Spell Level: 1st
A misty cloud of fog spreads in a 20-foot radius around you when you use this invocation, as the spell fog cloud. The fog does not block line of sight, but all creatures in the fog have concealment. A moderate wind or any fire larger than a torch immediately disperses the fog. The fog disperses on its own after 1 minute.
