Hi, I'm TC, one of the mods. The player who enabled at you asked me to answer. It depends on what you mean by headway against the antagonists. Can you kill monsters, yes. Can you defeat a ghost? Sure. But ghosts have a tendency of coming back, even if badly damaged the night before. Attacking a ghost or NPC and permanently damaging would require plotting with the mods, but we'd be happy to work with you.
