Working with Zakky's idea:
Missing Tongue: -X% Oratory, Leadership
Ugly Facial Scar: -X% Oratory, Leadership, Trading
Eunuch: -X% Leadership
Tattooed*: -X% Oratory, Leadership, Trading
Branded*: -X% Oratory, Leadership, Trading
Cut Nose: -X% Oratory, Leadership, Trading
*In this case, the tattoo or Brand would be something objectionable, such as the word "Convict", in a conspicuous area like the forehead or cheeks.
