The Witcher Bestiary - Drowned Dead
Drowned Dead Occurrence: The drowned dead are creatures of the night; they appear on the banks of ponds, lakes and rivers.

Immunity: Immune to bleeding, blinding and poison attempts; they are fearless, immune to stun attempts and the Axii Sign.

Susceptibility: Sensitive to silver and susceptible to knockdown attempts; the Fast Style is most efficient against the drowned dead; experienced witchers use the Group Style while fighting multiple drowned dead.

Tactics: These creatures poison their victims with cadaverine; they often attack as a group.

Alchemy: Cadaverine, Ginatz's Acid, drowned dead's tongue.

Particularly strong and dangerous drowners are known as the drowned dead. Simple people see no difference between the drowner and the drowned dead encountering either of them is equally deadly. We might suppose, though, that the most gloomy legends concern the drowned dead rather than drowners.
