A misty vapor arises around you. It is stationary once created. The vapor obscures all sight, including darkvision, beyond 5 feet. A creature 5 feet away has 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).
