Two questions RE: The sin card "Gossip":
a) does the player have to both subtract holy points and add unholy points, or can they choose to only do one or the other;
b) does the number of unholy points added have to be equal or lesser to the number of holy points subtracted (like an even trade).
Gossip allows you to add up to 2 unholy points and subtract up to 2 holy points. But neither is mandatory, and the amount you add and subtract does not have to match.
