Freezing Touch( Ghostwalk, p. 33)
Your touch is supernaturally cold.
Corrupting Touch (Gh) ,
You can make a touch attack that deals 1d6 points of cold damage. 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. If the attack scores a critical hit, the damage is doubled (ghosts are not subject to critical hits). 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 do not take this damage.
A ghost's touch attack normally deals no damage.
