Not sure if it's been mentioned or not yet but if you have level 30 hot time mules you can do the attendance really easily at the claw machine things in Kerning Square, I'm going to do it on 5-6 accounts (if I remember every day at least..) to unique pot all of my Root Abyss stuff, may as well take advantage of this as much as you can.
