Farmed for a few days, check the event page... 900ish neckties. Burn my way down until I have enough currency to buy out the entire trade shop for both phases... still have like 500 neckties left, on maybe the level 28 raid boss.

I think I overfarmed for this event.

In completely unrelated news, Russelia's chibi idle animation is oddly satisfying, how she bounces back and forth. Might be the first time I like an idle animation more than the main art itself. (Not that it's bad, per se, I just really like the chibi one.)
