The last team wasnt necessarily made up of poor students. As swordsmen, their level was equivalent to Lee Jang-hoos party, and Eom Hyo-seop (their wizard) wasnt especially remarkable but was accomplished enough to get by. If they were able to work well together, they would have cleared the dungeon within the allocated hour. However, their problems were apparent from the beginning of the video, taken by the camera installed in the dungeon.

Oh, its HOT!

[Stop with the magic, its getting in the way we can easily clear the dungeon without your help.]

Eom Hyo-seop used flame magic against the lizard-men, which was an appropriate response, but the swordsmen recoiled at the slightest burst of heat. From then on, Eom Hyo-seop shrank back he wanted to perform his duty, but anything he did prompt outrage from the rest of the team.

However, the party didnt struggle so much with hunting. There was another issue that plagued their mission.

Where are we?!

Are we lost?
