| Official? = NoYes

Using exactly the right words and the right tone, you instil doubt and uncertainttyuncertainty in your target. Slowly shattering the core of their soul.  Depending on how familiar you are with target and depending on the strength of his beliefs, it may take few sentences or few hours or not be possible at all.  If the maddening attempt is successful, the target will either cow and sob or try to attack you violently, then it will permanently suffer for the effects of [[Insane]] or [[Lost Faith]] depending on its personality.
