In japanese version, in second half there would be "super elite guard" units spawning, with 30 min limit. Then you get rewards for amount of super guards killed, 300 guards == SR card. Doesn't seem like nutaku did it right, tho.

Btw, is there some easy way to get Akie Ibara card I'm missing? Spent 15 card openers on gacha already and still no luck with her.

you can definitely get aki ibara, i've got her myself from rare gatcha, only thing is i had her from event gatcha so wasnt too happy lol

The easiest way is to just spam the normal gacha, I got Akie Ibara, Miyako Naruto and Runa Kamiwano at the normal gacha.
That's supposed to be the main reason of saving high amounts of Pero for this event. Just buy many N-Gacha tickets and be patient, no need to use card revealers.

Pretty much that. Although i got Runa from normal exploration before the event even started. Did anything about the second part of the event appear for anyone yet?

what the fk i can do with these 8mill bosses???

Cry? I think that is the only option for anyone not doing at least 1m damage in one strike at the moment (ot 4-500k with a few friends to help).
It's 7th July in my country now, not noticed any changes at all to the game.

As far as I know, the only difference is that we'll get to face even higher guards.

I've read something about ultra guards too, which have high HP and spawns during 30 minutes only.
I would be awesome if the other slayer cards started to spawn in non-event gachas too.
