Heroes Of The Clan have added a bunch of new features the last couple of days including upgrades to skills while leveling up, not only ratings. And today we added a new feature that allows the players to send out their heroes in the wild. Out there they face different kind of monsters depending on what zone they select but they might also end up facing an enemy hero if they're in the same zone.
It is a new feature but more will be added to it such as different type of class-defined skills. Rangers can track enemies, Assassins are harder to find, Druids can get intel by talking to animals and plants etc. This is not in the game yet, but will come soon.
