In the gameplay, players can find various types of bosses (usually at the end of each act) either in the Story mode or Trials. They are tougher and stronger as normal deaths and has got at least three active abilities each, with normal enemies having usually nothing or one.
In story, you can find all bosses as advancing further. They usually appear at the end of the level and at the End level mobs that must die in order to complete the level and exit the area by victory.
In Trials, killing bosses is your main goal. Not only that you'll finish the certain trial and unlock next ones, you'll also receive rich rewards after killing each boss. They spawn randomly I'm each trial.
- Each boss in game has his own background story that is described in the Books (story).
