Battle Modes (BM) refer to the different play styles which characters can play. Each battle mode allows the character to use the equipment and benefits that come with that battle m ode. Battle modes can be selected upon character login, and after the character has embarked on that battle mode. Characters can only play one battle mode at a time.
There are currently three types of battle modes that can be selected after choosing an episode to play: The Path System, Factions, and Devotion.
If you choose your Faction or Devotion BM, you cannot talk to your path mentor, path keeper, use your path set, nor earn path points.
