Tome of Magic Version[]
A mind fog is a physical block of fog that enables the wizard to weaken the mental resistance of his victims. Victims are allowed a saving throw at a -2 penalty to avoid the effects.
A creature who falls victim to the mind fog suffers -2 penalties to all saving throws against two categories of magic: all spells of the illusion/phantasm and enchantment/charm schools that affect the mind directly; and spells of 1st through 5th level which affect the mind directly. For example, phantasmal force is a mind-affecting spell; phantom steed is not.
The penalty to saving throws operates cumulatively with any penalties that operate for other reasons. Affected creatures suffer the penalty as long as they remain in the fog and for 2d6 rounds thereafter.
Wizard's Spell Compendium Version[]
Mind fog is a physical block of fog that enables the wizard to weaken the mental resistance of his victims, who are allowed a saving throw at a -2 penalty to avoid the effects.
A creature who fails the saving throw suffers a -2 penalty to any saving throw vs. spell for these categories of magic: spells of 1st through 5th level that affect the mind directly, and all spells of the illusion/phantasm and enchantment/charm schools that affect the mind directly. For example, phantasmal force is a mind-affecting spell; phantom steed is not.
The saving throw penalty is cumulative with penalties of other types. Affected creatures suffer the penalty as long as they remain in the fog and for 2d6 rounds thereafter. The fog itself remains for 3 full turns after it has been cast.
If optional schools or specialties are used, this spell affects the school of mentalism and any other specialties as decided by the DM.
