My table is going to take down a nemesis. This nemesis is a crime lord they attacked early games. Almost 100 hours of gameplay later, they stayed long enough onto the same spot (85 days in a row) Wich is nar shaddar. This nemesis came for them. I leave them 48 hours to prep to make the hit. I just don't know how many badguys or hired thug should I place in the same spot of the loan shark nemesis. I know my table is planning to go head first and guns blazing... And I want it to be quite hard for them but without making it impossible. So GM a little tips or alot would help. Yes it's me the GM who made the nemesis come to them. They still can run away or fight him. So what should I do ?
Thank you in advance.
