This is the only time you’ll face something like this, so don’t worry (more, that is)

About the actual boss fight

On the other hand, Khann himself is really easy. I don’t know if that’s good or bad for you, but for me—having tried to beat the gauntlets like 30 times—being able to defeat him on the first try felt like a gift

Have you tried using other crests? In my experience, certain crests make some fights ridiculously easy, while others can make them nearly impossible. The Wanderer’s Crest worked for me with this task, it let me take out enemies quickly and avoid getting overwhelmed.

I’m using wanderer+longclaw, but I also tried reaper, other crests I’m not really good at them, I only forced myself to use architect for the unravelled. I’m not sure which is better. With reaper I rarely get to land more than one hit, but I do get to land a pogo more often on the flying bastards

I’d recommend ditching the Longclaw (it doesn’t make that much of a difference anyway) and focusing on staying alive. I seem to recall using the Plasmid, the injector Band, the memory cristal and the Fractured Mask at some point to proceed (it’s been months since I did that fight, sorry my fuzzy memory).

My logic was: you have to stay alive and keep your health maxed out for as long as possible, use silk only to cure and beat the enemies either quickly or without getting too much damage.
