Sympathetic Magic, Starting Reputation

[10baseT]

Good morning, just a few questions for the group.

Starting Reputation
Page 82, upper right, Starting Reputation. Says most Free occupations add +5% and most Noble occupations add +10%. Looking at some of the occupations, Healer, Noble and Warrior for example, i don't see the bonus to reputation they offer. Is there a list i'm missing?

Sympathetic magic p387.
It says a sorceror can use sympathetic magic. Since it says 'can' does that mean it's optional?
If yes, it brings up more questions. Casting an air rune spell on Windsday gives me a 10% bonus, but casting a water rune spell on Windsday gives me a  10% penalty. So, since i'll be casting air rune magic most of the time, can i chose to have Sympathetic magic effect me only on Windsdays? What if i want to pick and choose other days? Or, what  if I choose to only have the bonus effect me and not the penalty, since it's optional? I think i'm missing something because my above doesnt sound right.

Thanks, Gil

I don't know of another list, but I might've missed it.  As for your second question, sorcerors are able to cast it.  What day they use it determines the bonus or penalty; it's not optional.  So if you try to cast a water rune spell and it happens to be Windsday, you suffer the penalty.
