How do I get the 4th chillmaiden I got 3 and got the mission egg but didn’t get her any idea how to get my last one I tried replaying the mission but haven’t got one any tips will help

Replay the misson, get the gold egg at the end.
What do you mean you didn’t get her? I assume you have to start from the first floor again.

Actually you can start on the last checkpoint

And by that, he means he didn’t get spin right

Just try to do it again until u get the 4th

Do I do it again from floor one or from checkpoint at floor 17

Checkpoint 17. Floors 1-16 will be a waste once you have gotten the first 3 chillmaidens.
