And I said 150+ total in 3 days to get the scroll to unlock it. The stage to get it can be ran 50 times. I reached max amount on it 3 times and got it after a reset again on the 3rd day. Not sure if my luck was just bad or something. Trying to farm some red background gear from chapter 3 and having the same problem again. 2nd day of trying to grab the Ninja Suit and still nothing, and these stages hurt as I constantly run out of units.
