Campaign mode is BloodRealm's main PvE content. There are currently four campaigns. Each campaign consists of six stages; each stage consists of six opponents, the last being a God. You may fight each opponent at any of 5 increasingly difficult levels as many times as you wish, though you need only defeat each once to progress through the campaign. If you complete level 5 you win a small Gold reward - 10 gold.
Each battle against an opponent in Rome, Gaul and Egypt campaigns costs 15 Stamina, with the exception of the Legion of Mars difficulty level 1, which costs 5 Stamina, and Ra difficulty level 5 at a cost of 45 Stamina.
Each battle against an opponent in Norse campaign costs 20 Stamina, with the exception of the boss battle at the end of each stage, which costs 25 Stamina on difficulty levels 1-4 and 50 stamina on difficulty level 5.
