After a long struggle, I managed to beat the Kayran. Great! Now I have a neat Kayran Trophy, a Kayran Hide, and other Kayran bits to round out my loot.
I know the Kayren Hide can be crafted into either Kayran Hide Armor, or a Kayren Hide Armor Enhancement, and the Kayren Trophy is already useable as-is.
But what use are the rest of the Kayren bits, specifically the "Kayran Tissue" and the "Kayran Eyes"? Are they just useful as relatively rare alchemical ingredients (contains Vitriol!), or are there more recipes involving them that I'm not yet aware of?
