I'd question the legitimacy of the word "event" in regards to Festival of the Lost. Handful of candles scattered throughout Social spaces, three part [b]objective[/b] based quest and useless masks. The most interesting and useful stuff (Sparrows, Ornaments, Emotes, Ghosts) that can be used after the "event" is locked behind a paywall for those who are unfortunate not to receive any as rewards in their three attempts, which is most people.
