A Katakan is a type of vampire usually classified as higher ones, however sometimes experts on the field of monsters like Geralt will classify them as lesser ones. The reasoning is possibly the age of the katakan itself, meaning that ancient ones are rated as higher ones and young ones as lesser ones. During a post-mortem autopsy examination, executed by Eskel and supervised by Geralt, it is revealed that the claws of a Katakan continue to grow during all its life, allowing a monsters expert to approximately calculate the age of the creature.
