"Back to the top!" In this episode of Semi Heroes, the companions continue making progress and getting back to the level they left. After leaving level 169 and returned gome to harvest, upgrade and improve, the heroes will make it back to level 170 and fight a big troll, who will prove to be quite a significant challenge even to this trained and upgraded heroes. Failing to beat the level once more it will become clear that they are not quite ready for this level yet, which will bring a new problem: to go back and improve again or keep trying.
