The Witcher: Masquerade - One shot

The Fiend is a massive, terrifying creature resembling a deer but much larger, with a stocky frame covered in rippling muscles and capped with a horned, tooth-filled head. It possesses a third eye located in the center of its forehead, which it utilizes to hypnotize its foes. Fiends inhabit dense forests, swamps, and bogs, typically avoiding human encounters but will kill when necessary, doing so with terrifying ease. Their sheer size and strength make them formidable opponents whose blows can easily crush a knight and their mount. Moreover, these creatures heal wounds at an astonishing rate, rendering them almost invincible in direct combat unless one employs loud sounds or relict oil to exploit their weaknesses.
