Quiet Type, Single Insight (3.5e Trait)
From D&D Wiki
Quiet Type, Single Insight
You don't say much...
Benefit: You may speak one sentence per day to one character. This single sentance will surely be one collected from all the observations you have made that day, and shall take the form of advice to one who needs it most. The character you speak to will gain an insight bonus equal to your level on one roll of your targets choice. This can be used within 24 hours of recieving the advice, or else it is lost. Not speaking for several days does not accumulate uses.
Drawback: Because you only have words for one insightful sentance, you rely mostly on body language and expression to communicate, thus any attempts to use skills involving speaking against sightless, blind, dazzled or creatures that otherwise can not see you clearly automatically fail.
Special: Spell casters must take Silent Spell in order to cast spells with verbal components.
Roleplaying Ideas: Either way, your character is quiet. Whether she is shy and passively observes the world around her or she actively chooses silence as a way freely hear what others say, your character is usually to back of the party, allowing the more dynamic and loud characters to create a screen you can hide behind.
