Here are some tips on setting the difficulty level. In Chapters 1 and 2, the quest maps should be played at 80% or 100%; otherwise, a large number of monsters may block the road due to weekly growth. In Chapter 3, you can experiment; you should have enough troops to deal with the weekly monsters. In Chapter 4, the troops of the allies and enemies are balanced, so use high difficulty levels. In Chapter 5, the hero is well-leveled, so choose any. In Chapter 6, set the difficulty to the maximum.
