Got a dressbloom and still waiting for the last prize to see if i need to do another run. Seems like the drop chances are 50/50, so it should be okay as there are 3 days

Btw, and a bit off topic, if i don't remember wrong not pulling any 5* in 2 10+1 rolls was like a 1/4 chance since i failed 2 out of 2, so failing 4 out of 4 should be 1/16 if the drop rates showcased in the gachas are correct. ....Which is more or less the same chance fo pulling a 6* in a 10+1 pull.
