Mask of Gentility

 
Prerequisite(s): Cha 15+, Bluff 9+ ranks, Disguise 9+ ranks.
 
Benefit: : If you are subjected to a divination spell that normally would reveal your alignment, your alignment registers as neutral. In addition, if someone tries to use the Sense Motive skill to get a hunch about your purpose or nature, she must succeed on a DC 30 check to obtain an accurate impression.
