This time we have a Raid Boss Event, meaning that the Event specific Bosses give a Currency with which you can by Star Lily and after that her Skill-/Dressblooms.
Pictures of the Maps and Strategies on how to do them will follow.

...so not one you nuke in a day maybe....could be 2

Looking from JP wiki, it's a raid boss hunt, meaning you will SPAM the event maps a LOT. Your objective is to collect event items and trade it for 5* and dress/skill blooms.

Apparently E-8 is the best one because it can spam 12 Million HP raidboss for 15 minutes which gives 500 for discover and 500 for poking.

So this event will be a friendlist check too?

I think you have to save some raidpoints for the big bosses. But since the timer on Raid Bosses doesn't start ticking until you leave a map, you could just see that it spawns and then ask in the Discord to see if some are ready to go full power on those. It also makes Power Gain after the 12-5 Clear way more useful.

I guess this time around I won't be sharing raidbosses to friendlist but to everyone. They usually die in very little time.

I'm still waiting for a slice girl....

what´s going on with this maintenance taking so long zzzzz

Long maintenance is loooooooong. Way to long.

In theory wouldn't this mean you can just leech off other people's bosses the entire event?
