Is it worth spending 15 mythril each on the FF6 and FF5 banners to try to get one of the haste SBs?
I'm at 275 mythril, but I'm saving for the orb fest draw thing (I'm hoping they're 25 each like last time).
So each of those banners is a 1% chance of that relic (plus a small chance of non featured 5* that could also be a haste relic) and you're doing 3 pulls.
Now the lucky draw is 11 pulls with a 12% chance of 5* relic (it could be 13% even). I've not counted relics but let's say 100 uniques (I think it will be more) 5 of which are haste (boon, lunatic, eiko, kefka, lenna...is that all?). In that case each of the 11 would be a 0.6% chance but the pull works out a lot cheaper.
The odds sound pretty similar both ways to be fair but the value is different and it is a matter of how much you value 30 mythril. Obviously pulling now means pulling more and that is the biggest boost to odds really. Of course there are big uncertainties like when the lucky draw and SSSB fest will happen (plus the contents of it) and also the quantity of lucky draws.
Not sure if that maths is completely correct though but it sounds about right.
As far as SBs go. Not sure if those are the haste SBs I want. Lenna's seems like a shame given scream doesn't feel too far off (but if you leave it to scream and don't get it you're out of luck assuming the weaker attack boost of Lenna's SB is still enough) and Kefka has the issue of magic becoming obsolete (can't build SB as fast and Ultimate bosses eventually have 2000 res which is a real nail in the coffin).
It might worth leaving it for the new quest system to come along as another do 1 pull get 5 mythril quest happens then.
