Defeat Bloodsucking Tatars in the Totem Trail area to collect Tatar Fluids. Then, talk to Yilmaz Karsh at the Woodcutter's Path. Use your quest tracker to see your progress.
Yilmaz Karsh: When you were fighting tatars before, I'm sure you Yilmaz Karsh: noticed the smell of the fluid they spray. NakanoAzusa: Yes, I almost threw up a few times. HiiragiKagami: It stinks worse than that disgusting fish roast ... Yilmaz Karsh: Fish roast? Um ... anyway, the fluid is actually Yilmaz Karsh: very useful in certain military situations. NakanoAzusa: What could that be? Yilmaz Karsh: For removing scent trails. NakanoAzusa: Scent trails?! Yilmaz Karsh: We have to be on the move soon, and Darkrane's army Yilmaz Karsh: will certainly come after us. Kynari and chepas use their Yilmaz Karsh: exceptional senses of smell to track enemies. We need Yilmaz Karsh: tatar fluid to throw them off our tracks. NakanoAzusa: I don't want to have to go near that stuff again, NakanoAzusa: but I see how it could be useful. Yilmaz Karsh: It's hard to detect the source of the smell, so our Yilmaz Karsh: enemies can't use it to follow us. We'll spray it behind Yilmaz Karsh: us as we go along. HiiragiKagami: Meaning you'll spray it everywhere we go?! Ewwww ... Yilmaz Karsh: Haha ... You'll get used to the smell soon. We all do. NakanoAzusa: I'll go get the fluid, but I'll leave the spraying to you.

Yilmaz Karsh: That's what I imagine a Zereca's breath smells like.
