Might not make it for the hidden quest

I aimed for Lv17, but it seemed like it would take too much time, so I gave up. It looks like I won't make it by the deadline :(_;´꒳`;):_ Tier 3 seems like it might appear, but it's being quite elusive. I'll just consider it a 'if I can, I will' situation. Either way, the rewards for the hidden quest are great, but I feel their determination to not let us get them easily 😅
