I got the Wizard Quest Buff, but momentarily got distracted. I checked to see how long was left on it, and it was 3 minutes and some seconds. So I did the quests as quickly as I could, but just as I bought the last item of quest 16, the Buff expired. T__T

Yep that sucks! The best thing is to do wiz quests first thing onsite. Then if you get the buff and don't notice right away you should still have time to a single quest.

Of course, I rarely do that 'cause there's always a ton of stuff to do :)
