Dark Campaign mode consists of acts and chapters that develop the story.


Dark Campaign consists of seven acts. The scene will be laid in places you’ve already been to during the Light Campaign. The adventure will take place at night, shortly after the journey of Roland and his companions.
A hired assassin named Sharazar is tracking Roland and his companions down. In order to return his daughter, he has no choice but to murder him.


Normal and Heroic mode 

Campaigns can be run in normal or heroic modes. You can proceed to the heroic mode once you've completed all chapters in normal mode.

Each chapter of the heroic mode can be completed no more than 5 times per day.
In normal mode, Shards are earned after completing a chapter for the first time. In heroic mode you can complete the chapter many times to earn Shards.

Energy 

You need Campaign Energy to complete chapters in this mode. Energy restores itself over time.

Stars

At the end of each chapter you will gain one, two or three stars. The number of stars depends on the number of heroes that survive the battle.
You can repeat 3-star chapters straight away by using Memory Spheres.
