Is it even worth running considering sta/exp ratio?
D'oh, you posted this as I was editing my post, so I'll just move it down here.
If it's 6012 runs for all of them, which I think is ludicrous, then I can't believe they had the time and money.
This is actually not as terrible as it sounds, especially since it sounds like multiple people were involved.
The things you need to pull this off are:
1) A really powerful burst team like Athena
2) A decent stockpile of money from Weekend dungeons (10m should suffice until the next weekend?)
3) A LOT of Athena (or other leader that is compatiable if not using Athena) friends, since you will be rapidfiring these
4) The ability to do basic math, use PDX, and time stamina gauges
I typically take the average of how much XP a run of the last level of the desired area I want to run gives (This rotation's seems to be 20,000 for 32 stamina, so let's use that.), and then chop up my exp remaining into fragments of 20,000, and multiply that by 32. If it's longer than my maximum bar or more than I can stand to wait to play PaD again, I'll grind it down with Goddess of Harvest or something to a more reasonable amount.
Let's say I get it down to about 59000 left, so that's 3 runs I have to do until a rank up. Assuming I don't fail, I just wait for 96 stamina and grind out three runs, rank up, and a bar of 143 stamina gets me 4 more runs for 128 stamina. That's 7 runs for a million coins, and also 80000 more exp into the next rank, making it over halfway to the next rank already. I simply wait a few more hours while doing schoolwork or something and -
what is this? I can perform another loop of 7/8 runs! This also gives time for enough Athena friends to refresh so I can do it all over again until I run out of money at last.
Money seems to be the actual limiting factor here, and I goofed this weekend not farming Legend hard enough and straight out going into the runs, so I'm poor again. I'm non-IAP and used absolutely no stones to do any of those 100ish runs, because the method is so efficient. With longer stamina bars I assume this gets even sillier, and I am trying to rank up as fast as I can so I can exploit this.
