Slightly off topic, but since there's no confirmed event yet, and this is a battling discussion, and training is part of battling (and we're theorizing as to whether or not using Order this week would be a good idea):
Checking historical dates, yes, next week has generally either been the end or the beginning of the Faerie Quest event. (Okay, so the year that it was in May was completely wacky.)
Apparently (and I somehow missed this),
a new banner has been appearing.
All that being said...it might not be a bad idea to stock up on certain quest items now, before prices hike. I've already made sure to have at least 2-3 of each of the Earth Faerie quest items and the grey Faerie items (there's such a short list for both of these!). Fire Faerie has a fairly short list, too, and some of those items spike pretty high, IIRC.
Lists:
Anyways, that all being said, I'm definitely holding off on buying a cookie until we either win the boon. Even if we don't win the boon, I might snag one or two if the event starts and they do discount them, just for future use for boons (should we end up battling for the Order again).
