Until they formally release a notice about the next event, we can't be sure that WB will be next (though we have been following JP pretty closely). On the chance that it is, please see the attached for a general guide:
For a general reference, please see the link below:
TLDR; Raid tickets are needed to kill raid bosses, you get 1 ticket per 30minutes, you can also get more by spending crystals.
For most stamina efficient: 1-2-1 (Ragna does not spawn on tutorial)
Realistically: Just do whatever stage you want, you only get raid tickets every 30min anyway.
Personally, I will be doing the Ragna story stages. Gotta get those fire mats for the aurora hearts.
Ok, so one question at a time:
Who should you 6* first? Eve, always attackers first, plus she will be your primary attacker for the upcoming Ragna
Who to level to 50 first? Depends on you priorities, but generally, the team you plan on using the most/ the soonest. Probably your water team in preparation for ragna
Would any other childs take precedence for 6*? No, Eve first.
Best Lineup for Ragna?
Eve, H Miku, Snow Miku, Mars, ChangE (leader)
Water weakness vs Ragna boss, ChangE buffing full team for faster fever times, and Eve for massive damage during FT.
I would recommend using this fodder list:
Feel free to fodder anything without a symbol.
I agree with half of this post. While the screenshot was unnecessary, I appreciated the statistical work that went into this post. There have been many people that, like you said, saved up for weeks on this banner only to get nothing they wanted. Understandably, they are upset and are coming to this site to vent their frustrations. That being said, calling the RNG rigged or terrible just isn't fair to the DC team.
This game is probably one of the most generous when it comes to f2p content; they are basically throwing 5*'s at us with all these events.
Extract them for onyx, the only 3* childs to keep are Mona, Lisa, Davi, and Tiamat.
For a list of useful 4* childs, use the less useful childs as evolve fodder.
ChangE, Dana, and Maat are who you are looking for. Often considered the holy trinity and can easily carry you through all the story.
For a Re-Rolling Guide:
You guys can refer to this for optimal stamina use:
Great work! It looks like one of the assumptions you made was that the stamina use during Hot time is 2x as effective. This is only true in terms of experience and does not account for childs/ equipment gains.
From your numbers, using all your stamina during the week results in approximately 6% less experience:
(6438-6058)/6438 = 5.9%
But, this means you run 1220 stamina worth of less missions.
(1244+3570)- (2844+750) = 1220
Assuming about 12 sta per mission, that's over 100 missions less for a 6% increase in xp.
Use all Sta during week = 100 more missions
Use only 120 Sta during week = 6% more xp
