When this spell is cast, the wizard creates a billowing mass of misty vapors. The area of the fog is 2000 cubic feet per rank (20' x 10' x 10' section per rank). At rank 21, this increases to 60,000 cubic feet at rank 21 (about 10' x 80' x 80'), and 100,000 cubic feet at rank 22 (10' x 100' x 100'). The caster can create less vapor if desired, as long as a rectangular or cubic mass at least 10 feet on a side is formed. The fog obscures all sight, normal and infravision, beyond 2 feet. However, unlike normal fog, only a very strong wind can move these vapors, and any creature attempting to move through the solid fog progresses at a movement rate of 1 foot per round (+1 foot per point of STR above 20). Large creatures can move at a rate of 5 feet per round (+1 foot per point of STR above 20). Giant creatures can move at a rate of 10 feet per round (+2 feet per point of STR above 20).
A gust of wind spell cannot affect it. A fireball, flame strike, or wall of fire can burn it away in a single round, causing 4d6 damage to everyone in the fog as it does so (save for half damage). |
