You have a habit that would be harmless if it didn’t betray
your efforts to be cautious or deceitful; e.g., “Bites fingernails
when nervous,” “Cracks her knuckles before a fight,” “Gestures
to cast spells, even when unnecessary,” “Hums subcon-
sciously,” or “Wears Chanel No. 5.” Treat this as Obvious
(p. 14) in situations where it would compromise concealment
or surprise, or as Distinctive Features (p. 14) when it would
mark you as a specific, known individual.
What makes this one quirk rather than two is that it isn’t
“always on.” Either it’s tied to an activity, such as spellcasting
or fighting, or an ally could help you avoid it (remind you not
to do it, offer you different clothing, etc.) without wasting
appreciable time or rolling against a skill like Disguise. If both
Distinctive Features and Obvious penalize you constantly, take
those instead.
For a supernatural variant, see Spell Signature (p. 34).
