Oh yeah, don't get me wrong, if someone is having trouble with it, it's best to train. I just wanted to remark that there's more to take into account to clear it han just power, since you can see some people clearing reliably with 50K teams or so, and some others failing misserably with 60K teams. As someone with units not suited for the map, i wanted to warn the people in the same situation.

So far what i'm doing is going for the chest with a really strong helper i know i can count on to kill/weaken the boss reliably unless some really weird shit happens (last run random arrow only allowed a team to go up after the 7th try and still killed the boss with some margin to spare), until i can get Mountain lily to lvl 5 skill. After that, i'll forget about the event and farm 12-3 as usual and go back in the last day for the 2 flower gems and that 10% affection object.

But i would like to be able to clear it on my own...it hurts my pride a bit D=
