uh........ you are saying you got 37 5* orbs in 4 days? You have some serious luck with that...
Yes (plus more with conversion), but I did also do 27 mythril refreshes as noted as well as min/maxing my stamina during that whole phase pretty much. Out of curiosity I just did the math, with my natural stamina plus the 27 full refreshes that 4 day window gave me virtually exactly 6,000 Stamina total. I lost ~40 stamina or so from sleep etc but that's whatever. 6,000 stamina divided by 37 natural 5* orb drops is ~162 Stamina per single 5* orb drop, which I don't think is unreasonable? I mean I wound up practically speaking with more than that with conversion, but getting about one 5* orb per current full maximum Stamina refreshes seems not crazy.
But yeah, I think my orb rate drop was at the least solid which is why I'm happy with the mythril spent to be honest. Plus I was doing virtually all of this while stream monstering Final Round nonstop the last two days so it wasn't soul crushing or anything. Gonna go in hard this phase as well, I'll be relatively busy for phases 3 and 4 so I'll do what I can there but I likely won't get nearly as many refreshes there as I will the first two, so my rough budget of 75 mythril for refreshes across the event will work out pretty well.
