Ok this one is not really one but god damn i love it. So in dark souls 2 you had covenant to fulfill in order to unlock stuff, one of those was a PvP thing where when someone got to an area you where invoked into their world to kill them and you needed to do that like 30 times i think ? but you could do the offline alternative where you had a 12th of a chance for a special ennemy to appear and killing it counted as a player. 1/2
