The Witcher Bestiary - Garkain
Garkain Occurrence: Garkains are lesser vampires, found most frequently at cemeteries or near abandoned buildings, where they nest.

Immunity: They are fearless and resistant to stun attempts.

Susceptibility: Sensitive to silver and Vampire Oil.

Tactics: They try to daze their victims and drink their blood.

Alchemy: Garkain saliva, wing membrane, and abomination lymph.

Garkains, the filthiest of vampires, are uglier even than fleders. Since fleders are widely despised for their looks, it is easy to imagine how abominable garkains must be. As vampires, the creatures drink blood but they are also drawn to fresh meat, or even corpses. Garkains are often mistaken for gargoyles because they lurk on rooftops, waiting to dive at their victims.
