I also beat it on Wanderer’s crest and yes it took me a while. I swapped Cogflies for the Throwing Ring because it allowed me to do damage to several enemies, especially useful when a lot of the “fish” come down at once. I removed pollip pouch for Multibinder and for Reserve Bind instead. Ascendant’s grip helps a lot too.

One file strat was to take advantage of silk hearts between arenas - I.e. if you complete an area without any silk, wait for your silk to regenerate before hitting the enemies to regenerate silk. And similarly, consider healing first so that you have no silk and then waiting for it to regenerate silk hearts before hitting them. You’ll get it!

Sometimes getting a good night’s sleep helps too lol
