I don't plan on doing anything elaborate, I just want to be able to customize enemy placement and item placement. My plan is to make a sort of "scholar of the first sin" remix for Dark Souls, so I don't need to mess around with anything advanced. What tools am I supposed to use to be able to mod the game? Is PTDE or Remastered easier to mod? I'm very new to this, so any help would be appreciated.
