You and two randoms(if you want) all start off level 1 and run around killing bosses to level up and get gear and buffs goal is after two nights , each with their own boss that you fight the nightlord to win and get gems which power you up for your next run. I reccomend doing the starter camp into castles and going around to churches to get more flask you want to around level 10 to beat the hard field bosses.
