Corruption can be increased in a number of ways. One way to get a few points is to steal logs from the log piles outside of John's Smithy, The Drunken Fox, and Katherin's House; you can steal them after having started Emily's meal quest. Another way is to give cumwine to characters Penny, Katherin, and Kate, maybe Hiba and Ayita. Another is to spike Tia's mug of water with cum before giving it to her while she is cutting wood. Another is to put cum into the holy water in the church. I believe having sex with Gwen on the stone slab is another source, though not so sure on that one. Also spike Yasmine's tea in the mayor's kitchen before Julia serves it to her. In general, any opportunity to get a woman to drink the MC's cum without them knowing it will increase the MC's corruption.
Q1. I have already brought water to Tia, can I still bring water to him?
Q2. Having sex with Gwen on the stele did not increase the corruption of the MC... Did I fail to do any of the steps?
Q3. I put MC's semen in the mayor's wife's tea, and the mayor's wife did not increase corruption after drinking it!
Q4.If I sell the bottle with MC semen to Lucius will it give Kate influence to go to NTR? (closed NTR)
