Wall of Fog (spell)

Wall of fog conjures a dense wall of misty vapour that greatly limits visibility within the affected area, including infravision and ultravision. The fog may be created anywhere, over land or water, passing through the middle of buildings or along a corridor, as high or as deep as the caster wishes within their ability.

Wall of Fog

Range	30 ft. +10 per level
Duration	2-8 rounds, +1 per level
Area of Effect	six 10 ft. diameter cubes per level
Casting Time	1 round
Saving Throw	negates
Level	illusionist (1st)

The fog is completely harmless, though creatures with an intelligence of less than 4 will "go to ground" in it. When the spell's duration comes to an end, the fog will require three complete rounds to evaporate, improving visibility by two hexes each round, until the effect is completely gone and full visibility is restored.

Visibility

Within the spell's fog, visibility equals one hex exactly; combatants can therefore fight hand-to-hand within it, at no penalty to hit or damage, but missile weapons are useless. Attack spells can be fired blind, while audial-based spells, like chant, audible glamer and magic mouth, are strengthened in that their sources are invisible.

In any hex adjacent to the wall of fog, visibility equals one hex when looking into the fog, three hexes when looking along it and completely normal when looking away from the wall.

To those further out, the visibility of persons standing next to the fog is normal; however, those inside the wall are completely invisible.
