So far:

10 Stamina map = 40 Dolls
20 Stamina map = 85
40 Stamina map = 240
50 Stamina bonus map = 345

I got Primrose on my 2nd 10 Doll pull, nice but much better to have the early pull luck the later Gachas where single pulls cost 100...

Looks like we need 43,000 to clear wk1 and 40,000 to clear wk2. That is 345 runs at the 40 Stamina map or 28.8 days worth of Stamina LOL.

Not got enough Rice Cakes yet to see how many we get on that 0 Stamina map.
