One who knows himself but not his enemy

It was a strange beast that looked like a griffin drawn by someone on drugs. It had a body of a lion and leather bat-like wings… there the similarities ended. The beast's tail was that of a scorpion and ended with a stinger that almost dripped venom. Instead of a lion's muzzle, the monster had features that were creepily close to a human face, but with sharp teeth of a predator.

I tried to remember if Rosha or Yvenna told me about monsters like these, and something sprang to my mind. It fit a description of a mantichora, a more chaotic version of griffins. Its venom was deadly, and the monster itself fairly powerful. With how high in the mountains it lived, though, the meetings with it were rare.
