Kikimora

"Then the kikimore princess summoned all her loyal sisters and off they went! Together they charged the enemy trying to harm their queen.
– “The Kikimore Princess and the Mountain Giants”
Cornelius Briggs (dwarven children's fable, fragment)

It is unknown how exactly it is kikimores communicate with each other. Autopsies are hampered by the high toxicity of their subjects. Scholars have established that kikimores do not seem to possess any detectable auricles. One amateur researcher, Count di Salvaress, put forth a theory in his treatise “A Microscope Among Monsters” suggesting kikimores have a highly developed sense of smell and use airborne particles undetectable to humans to transmit information. This theory has yet to be proved or disproved.

Kikimore warriors defend their nests from attackers. They attack somewhat slower than kikimore workers. They are able to spew streams of caustic venom a great distance and leap to attack. This venom is highly unique in that it reacts with a witcher's body to raise the level of his potion toxicity. They are covered with thick, hard armor which easily deflects blows from even the sharpest sword.

Kikimore warriors are protected by swarms of workers which obey their orders until they are themselves eradicated.

They are completely immune to the effects of the Axii Sign, but vulnerable to Igni, oils and bombs harming insectoids and blows dealt by a silver sword."
