Speartip is a Creature/Monster in The Witcher 3: Wild Hunt. Speartip is a Cyclops.
"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?
— Odess Thaka, traveler. Died tragically on Spikeroog
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."
