Once there, the group should find a room behind a level gate, and inside it, four boxes and a lever. All four daredevils should stand on the fields (the strongest knights at the beginning, that is, closer to the lever), and when they are ready, pull the lever to the left (it can be used only once a day, so if it is already set to the left, it means that someone has already used it today and you have to try to complete the quest the next day):

The group will be taken to a cramped room with 6 Demons, 2 of which block the way forward - only they need to be killed to move on:

Once these 2 Demons are defeated, DO NOT move on quickly, step by step you approach the reward room, carefully watching your life level and constantly healing quickly to get to the reward room. Everyone can choose only one of the four rewards. Once he takes one, he should head to the teleport on the right, which will take him under the level gate:
