so when the girl that get too corrupted cant get pregno uh
also is corrupted strats easier to do than chat/give them gift and what skill i should priotize?
Best way is definitely to corrupt them first, and make extra sure to use the VCR on their defloration for massive money yields that removes any need to grind. With money in hand, always buy out the shop every day, especially the Pure- and Mysterious Ink that is available every 6th and 11th day (I believe), which will reset the corrupted girl and grant Love Stamp straight away and allow impregnation.
Rinse repeat for every heroine, but for the ones after the Captain, consider feeding them Strange Ink first to speed up the initial corruption and surrender points.
