Hellow, first I want to say thank you for the upload ^^
Personally I find this game very funny ^^ Probably because it's ridiculous, I'd really like to be able to finish the hard mode, but Im kinda stuck, I found the guy that raise my "talk skills" but I can't find the one that knows about tools and potion ( for sabotage )
For tools, in the west side of town, there is a house in the bottom left. In there, there's the tinkerer. I think you just need to talk with her, then you have to talk with your father. If the father talks about the tinkerer and gives you an accessory, go back to the tinkerer's house, and she'll give you the skill.
For poison, go to the graveyard. One of the graves is differently colored. Keep visiting the grave, and eventually, a ghost will pop up. He'll ask you to investigate his mysterious death. Go to the inn, and talk to the innkeeper. You'll get a seal from him. You might have to talk with the waitress in the pub after that. Then, go to the prison, and talk to the prisoner in the top right cell. You'll know him because he's the only one who isn't near the bars. Then, go back to the ghost, tell him everything, and he'll give you his knowledge of poisons.
