Sylas was fairly confident in getting this far, but for the next steps, he would be flying blind, not to mention the fact he was on a time crunch.
He could still withstand the chilling wind for longer, but once he started to focus on this task, it would surely begin to take up his Wisdom. By then, he might start suffering again.
It also had to be remembered that he had to complete this round within 50% of the time Brisa took to complete it. Or else he would be disqualified and fail the Dungeon. By then, all the work he had done would be useless.
The good news was that he had only taken a few minutes to get here at most, thanks to the time crunch that had been his fusion time limit. The bad news was that he still wasn't sure how long this would take.
But he hoped that the risk would be worth it.
