Cyclopses - The Witcher 3

How about this... we take a big stake, sharpen its tip, jam it in the cyclops' eye – then sneak out of the cave disguised as sheep. How's that not a good idea?

Cyclopses can easily be recognized by the single eye located in the center of their foreheads. If for some reason that is not visible, other tell-tale signs are their enormous size, incredible strength and a seething hatred for all humans.

Evidence suggests cyclopses can live for an incredibly long time. The one well-preserved specimen whom scholars have examined and documented – a body found in 1112 and taken to Oxenfurt specialists – was over three hundred years old at the time of its death. The remains of this specimen could until recently be seen in the Academy's zoological museum, but they were removed from display after students tried to dress the cyclops in a toga, damaging it significantly in the process.

As in the case of giants, one can only guess at the strong and weak points of a cyclops. Its heft alone precludes effective use of the Aard Sign, while its enormous physical strength would make its blows particularly deadly. Cyclopses are most likely vulnerable to ogroid oil. As monsters with relatively well-developed minds, they might also fall under the influence to the Axii Sign.
