Hi I want to ask about getting past the second floor stage in the cave He asks me to corrupt my soul with ghosts but after I do that he takes me out of the cave I would be grateful if you would give me the necessary steps to get past this stage
You need at least 15 Point of Corruption. That's basicly 15 loses against ghost. Better use up all your money for beer, rum or whatever items before going onto a losing streak.
There is also a way to bribe the guards (CHA?). I haven't tried that.
