I could give or take the succubis. All I really wanted out of this event was the Reesa card, which is looking doubtful now.
My stamina caps every 4 hours, so I've been trying to log on 4-5 times a day to progress through the dungeon, but I've only gotten to about floor 80 so far, and I don't think I have enough tonics/chicken to burn through the rest. Did anyone get to 100 without using items? I guess it might be doable for a low-level player with free stamina refills @ levelup, but it otherwise seems really difficult.
