Thanks! ^_^

I see that you are having trouble clearing E-3. Have you cleared that map in the meantime? I am sure you're already aware that the boss can be weakened in E-3. Did that actually help much? (I still need to update my guide for E-3 for the weakening mechanism..)

If you want, you can post a replay here and let me (and perhaps other people too) examine your situation. I'm not saying you're necessarily doing something wrong though, it might indeed just be very bad luck. :/

As you can see, I didn't manage to score many boss kills and S ranks either: 19 Attempts, 16 boss encounters, 2 boss kills, 2 S ranks

Also, I don't want to discourage you, but E-4 is the hardest map of the event imo. Are you confident enough? Changing difficulty there means resetting the TP phase as well, I believe. That be a waste of resources. But you never really know until you've tried it! :O

Good luck anyway! ^_^
