I'm curious what other GMs have done with the sin points mechanic in the AE. I'm thinking about scattering a number of encounters throughout the AP that specifically give the PCs a chance to be sinful or virtuous. While these might be combat encounters, I'm really looking for situations more like the Shayliss/Venn Vindner encounter to really tweak my players and give them chances to explore their character's sins.
So what have you done, or what ideas do you have for encounters that give characters the chance to be Envious, Gluttonous, Greedy, Lustful, Proud, Slothful and Wrathful?
