True, if you have a weakness for smelly feet (it turns out after worshiping boots at night 3 times), then it has a very unpleasant ability if you lower health level to less than 30%. This is a classic trap of the author of this game, it is quite true. To overcome the stage when she presses your boots to your face, you need to resist. You will have to go through a rather intimidating QTE, but if you successfully break out, then you will have no debuffs on the attack, and you will finish it off without any problems.
It should also be said that every third move she defends herself, and if you attack at this time, she will acquaint you with her hips more closely (undoubtedly, this will delight you, but the health bar will not delight). I advise you to always defend yourself, because in this case your health hardly drops (I left with almost full health points sometimes)
If you reach level 10, you can take over 15% of the damage, and if you damage her when she raises the shield, she will lower it without problems, then you will finish off the remaining 15%. Quite a tricky trick that I did by accident.
Edit: In general, I can just give a version where these QTEs are slowed down, but this is already some kind of cheating, it's easier just to increase your attack through the save editor (I think 150 bonus points will be enough to take 80% of her health points, and 300 enough to bring her to her knees with one blow)
