Beauty affects a few secondary stats:
- Reaction modifier: this is the superficial and sadly inevitable response which may be occasioned by one's physical appearance. The character receives this bonus or penalty, upon first meeting any NPCs.
This reaction modifier affects shop prices. A higher modifier means cheaper bought goods and more money received for sold goods. This shop price is a percentage markup.
A high Beauty is needed for certain dialog options. Among these are getting a kiss from pub women as male (14), seducing Lillian Misk (unknown), and indirectly (this is actually based on reaction modifier, so things like a fancy dress can help) lowering the price of getting an invitation from Mr. Wellington as a female (if high enough, one can avoid pleasuring him).
