Is there an actual spell like the one that comes with the madness domain listed bellow? Personally I think the spell is epic.
Vision of Madness (Sp): You can give a creature a vision of madness as a melee touch attack. Choose one of the following: attack rolls, saving throws, or skill checks. The target receives a bonus to the chosen rolls equal to 1/2 your cleric level (minimum +1) and a penalty to the other two types of rolls equal to 1/2 your cleric level (minimum –1). This effect fades after 3 rounds. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Guess not :(
Were you looking for spells with a similar theme, or with a similar effect?
I think there was in 3.x but I don't think PF has one.
