It's like Agrias. They are making the cost of 4-5 roughly about the same as 3-5 would have been had the units not been 4* base. They'll probably do it with the 4-5 upgrade for WW Fina too.
I really need to spend the rest of my auracite today. Still have about 8600, but I can't decide whether to get the mats for Cecil (not going 6* until LB is done, at minimum), CoD (should be the next 6* release), or just buy an equal amount of each to be mostly prepared for any future use (like WW Fina). It's a given that the Halloween event will have 6* mats for sale on King Mog anyway. I'm hoping to finish the event really early and go back to TMs though.
Would be:Ok I cannot get the math right.
How do I calculate summon probability? For example, if I do 11 pulls with a 12% chance for the unit I want, what are the odds that I will get at least 1?
Ya no. You would want to use the binomial distribution to calculate the probability as I stated above, which would give a 36.7% chance.It's just 1-((1-0.12)^11) = 75.5%. You calculate the probably of not getting it in 11 pulls and invert the %.
This is a great chance to restock some Lapis and tickets and then blow it all trying for Orurandu.
Oh well, at least it simplifies everything. Pull Lid with dailies since she'll probably have close to 20% rate in this banner, then full stop.
