The Purple Onion are famous (notorious?) for our lackadaisical laziness and forgetfulness. We have often gotten into LW and forgot about it until the round was over. Strangely enough, we still managed to win gold once (and a few silvers) and people have asked how we do it.
The answer: we don't know.
Anyway, I would like to share a really easy way to win gold in Chrono (with the added bonus of getting bumped into the higher division so you will have a REAL reason not to bother to do anything for a while afterwards).
STEP ONE:
You have to join a chrono event. Assuming that you already know how to find it (under battle -> climb), and how it works, you will need to ACCIDENTALLY join one the moment it starts, preferably within its first hour. The timer cuts off at a random time, so the sooner within the hour, the better. The problem is, we don't know when it will begin, which is why I say you have to accidentally do it.
STEP TWO:
Do nothing. Just forget you joined and after a few days, login to your profile to find a trophy and several reward cards.
IT'S THAT EASY.
