Evil Brand

(Book of Vile Darkness, page 49, DnD 3.0)

[Vile]

The character is physically marked forever as a servant of an evil power greater than herself or as a villain who does not care who knows that she seeks only death, destruction, and misery for others. The symbol is unquestionable in its perversity, depicting a depravity so unthinkable that all who see it know beyond a doubt that the bearer is forever in the sway of the blackest powers.

Benefit

Evil creatures automatically recognize the symbol now emblazoned upon the character as a sign of her utter depravity or discipleship to a powerful patron, although the specific identity of the patron is not revealed. She gains a +2 circumstance bonus on Diplomacy and Intimidate checks made against evil creatures.
