what does beauty stat actually do apart from the few negan quest requirements and slave market vip fullfilment? does it have any impact on their other day to day stuff? are extremely ugly street worker less likely to meet clients? also does the nympho trait impact gloryhole worker?
Beauty appears to have the following effects:
Increased pay as a street worker
No effect on whether they find a client or not
Increased sell/buy value at slave market
Increased likelihood of another Guest NPC choosing to have sex with them (specifically male guests wanting to have sex with female slaves spontaneously, or guests wanting to have sex with other guests that fit their preferences ie "Likes girls" whether spontaneously or by player requesting they have sex with someone)
As for Nymphomaniac:
Will never decline sex with player
Will never decline sex with other NPC
Increased pay as a street worker
No effect on whether they find a client or not
Increased pay at night club
Will not experience relationship decline if (as a slave) offered to another slave, including if creampie allowed
Does not effect slave sell/buy value
It seems neither of these factors effects whether they find a client or not. As long as they work a shift, their likelihood of finding a client is inversely proportional to their likelihood of dying. Higher strength and carrying a knife both decrease chance of dying, and accepting Dom's proposal drops chance to die to zero.
That said, they will not work during a sandstorm and will not work if their happiness drops too low if you have automation setup in an established colony. These are the only situations (that I can think of) where they will be assigned to street work, not find a client, and not die.
To get the most buck for your bang out of your street workers,
accept Dom's offer (which is story related so just go with it anyway)
max out the following stats: sub, beauty, pussy, anal
don't send your whore out in a chastity belt. That would be silly.
Nothing else matters here. No other traits increase income.
