Kinda silly to rehire the voice actor for just 2-3 more dialogue lines.She doesn't do anything, other than comment on your progress through act 3. In fact, after you finish quest 6, she will disappear forever.
She basically serves as foreshadowing for the assassin class, which came in the expansion. Actually, I'm a little disappointed that she doesn't have any special dialog for the assassin.
Every time you click a noob gets his wings.Nah, just a flavor NPC. I think she was there prior to the LoD expansion, so in a sense she may have been like a teaser for playable assassins in the expansion.
But I've heard if you click on the chat gem exactly 99 times, then run 3 clockwise laps around Kurast and then talk to her......
