Oh, You didn't had the Pale Nails? I think I forgot to mention that by the time I went to defeat Khann, I had already found or bought almost all the tools and upgrades. I'm terrible at gaming, and usually, what I can't achieve through skill, I make up for by finding upgrades to make things easier for myself.
You didn’t have Ascendant’s Grip? I’m surprised you didn’t lose your mind during the Mr. Mushroom mission. I almost did, and I already had Ascendant’s Grip at that point.
Reaper's Crest is one of my favorite crests. it's so versatile, and I think I also defeated the Pintress with it.
Anyway, I'm glad you managed to defeat Khann. Is that the last heart you needed, or do you have more left?
