Square Enix announced via the Lodestone that the Halloween Seasonal event “All Saint’s Wake” comes to Final Fantasy XIV: A Realm Reborn starting October 19th and lasts until November 1st.
You can check out pictures and information on the quests and rewards here.
Essentially, it looks like the clothing rewards are Glamour items to deck your character out like a Werewolf. Kinda neat. The other rewards are all housing related, which kind of sucks considering the housing expansion that just launched wherein all of the houses were gone in a matter of minutes. So…depending on how long the quest (or quests) is I may get around to doing this or not. I guess the housing items could sit in our free company chest until needed.
