Conquest Battles, a feature introduced to the series in Odyssey, return in the form of "Assaults" which see the player lead armies to attack fortresses.[5] "Raids" are smaller engagements where the player leads a raiding party to attack a target and secure resources for their settlement.[5] The player is able to build a raiding party by recruiting non-player characters to assist with these.[17][13] The player is able to create a Viking mercenary, or Jomsviking, that can be recruited by other players to act as a non-playable character within those games; the player gains additional in-game rewards for successful missions that their Jomsviking takes part in.[17] As part of the game's first season of DLC content, an expanded "River Raids" game-mode was introduced which offers replayable raiding locations in new regions of England not reachable in the main map.[18]
