From their description, it didn't sound like they had gotten any sort of reward. Karl suspected that the Awakened Rank group had gotten something, as they had at least finished the first two waves, though they nearly died on the third. That was nearly as good as his team had managed, and they got new skills.
It was impossible to tell how Prince Corbin had done, as he was in no shape for questions, but the rewards that Karl's group had gotten seemed pretty impressive.
"What do we do now? We finished the challenge in the room, but do we dare to keep going?" Karl asked.
Prince Corbin laughed. "Finished? Oh no, that wasn't what finished looks like, at least not from my side. I suspect that was intended to be a group battle."
"Well, technically we lost as well, but it's over now and we're out. Three people was barely enough to get through, but I think that five at the same Rank would have been better." Karl agreed.
