I have a question about the witch that you have to kill in order to find Oscar and save Lea, how is it even possible to kill her through 3k hp? Do I have to be even more overleveled or are is it easier on magic/prayer? Also, I got the bad ending already but would killing the witch change anything at this point or is Lea stuck in the village now?
My English is bad but I'll try to help you
The order is this in the 2° floor
Update your equipment. Get the best also for your character in the little shelter when you'll get the VIP card.
Go to the bottow of that map until you reach the section of the south of other map.
In the map you have entered. Go to find the recipe that would give you invisibility that is located near the east southeast part of that map. Be prepare there is a some kind poisonous monster "caring" that recipe.
Next
WITHOUT EVEN ENTER THE VILLAGE OF THE FANATICS, so don't go there for the moment. Because if you enter that place or eat the rotten sausage the EVENT to rescue Oscar and Lea will start to trigger
Next "empathize" will bastard Ned. That is below the door of the next level, until he'll be "fuck buddy" with your MC. Those are 4 or 5 events. That bastard would activite at least 2 of those "torches". But be careful your MC will have to fuck and return to the main village in the game. I don't remember is you "discover" before he's ploting agaisnt you there were no more "porn events". So is better is you tap to return and don't explore during that time. But once you complete all of those events you can face that mf ( it's better if he actives the most difficult "torches").
So, if you did all of this you'll get 3 of those " torches" active and you only will have to conquer the last one... and defeat the gray "witch" . Doesn't matter if you kill her. I've read she's strong and inmortal( she'll revive later in that village even if you kill her).
In that "demented" village it's better if you update your equipments "talk" with Lea and NEVER eat the dish the " gray witch" will offer. You can be there 3 days or just buy one Rotten Sausage in the village and give that to the pig in some of those houses. Next go to the southeast part of that village ,and there is a house and you have to put the "paper" that pig give you in exchange of the rotten sausage. Next take a nap. And rescue Oscar that is in the shelter of that " gray crazy witch".
