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


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.
