1.4 is kinda boring.
First half is Wind-bloom festival and bunch of mini-games.
Second half is battle tendency.
Banner wise, first half venti, and second half some standard banner 5* with rosaria.
not sure who yet.
1.5 is probably Chasm. It's still probably speculation.
It'll come out for sure but not sure when. It's probably soon.
I hear that there is part of the plot regarding the cloud retainer.
There will also be a physical damage claymore 5 star character, not sure if they're the cloud retainer.
It's a probably a cryo claymore and is probably plays with superconduct reaction a lot.
not much information out there.
1.6 is probably going to be prelude for inazuma.
Plot in inazuma was redone completely and it's probably complete by now.
there was an image where 1.4 is inazuma but it was changed. but it was later taken back and redone.
it'll be at least 1.6 before we see anything related to inazuma.
And 1.6 would have the prelude stories to inazuma.
After 1.6 is just 2.0 where inazuma full launch
