The Witcher Bestiary - Echinops
Echinops Occurrence: Echinopsae grow in places where crimes have been committed or on the graves of the victims of such crimes.

Immunity: Immune to any effects which influence the mind (fear, stun, Axii Sign); they feel no pain and can neither be poisoned, blinded, knocked down nor bled to death.

Susceptibility: Echinopsae are sensitive to silver and highly susceptible to incineration attempts.

Tactics: Echinopsae are rooted to the ground, but they shoot with poisoned thorns.

Alchemy: Echinops rootstock and spores.

Echinopsae are monstrous plants which grow in places where terrible crimes have been committed. The beasts try to take their vengeance on criminals, but they do not spare the lives of innocents who haplessly enter their territory.
