HeroesLAND is another “online heroes” game.

Factions Competition
To improve combat and political skills, a Factions Competition is starting in HeroesLAND.
The Council of Factions pays special attention to battles involving all heroes, from young to old, but research is also being conducted on other parameters that may be taken into account in the Competition.
Each week, all heroes of the faction that scores the most points are awarded "Days of Immortality" - even if they lose in battles, their artifacts will not break, external units will not disappear, and first-level pets will not die. After that, the accumulated points are reset.
Information about the current state of affairs in the Competition is provided by the Herald in the Tavern.

I don't quite understand what you mean. Please explain.
