Nauseating Touch( Ghostwalk, p. 37)
When you touch a living creature, you can make it nauseated.
Corrupting Touch (Gh) , CHA 13,
You can make a touch attack that nauseates a living creature for a number of rounds equal to 1d4 + your Charisma modifier. The target may resist with a Fortitude saving throw (DC 10 + 1/2 your HD + your Cha modifier). When you are manifested fully or attacking incorporeal opponents, you add your Strength modifier to attack rolls. When you are incorporeal, you add your Dexterity modifier to attack rolls. Only one kind of damage or effect from the path of the corrupter applies from each attack.
You do not have to use this ability when you touch another creature, and creatures that touch you are not subject to this effect.
A ghost's touch attack normally deals no damage.
