Razorback Nightcrawler | Dark Souls 2 Wiki

This giant millipede is found only in Black Gulch. In contrast to the artificial creatures roaming The Gutter, the Razorback Nightcrawler is a product of an undisturbed evolution. They are more capable of crushing a careless passerby with their great weight and tremendous power
Enormous, many-eyed worm monsters that crawl from their hole-lairs in the walls of Black Gulch. Because they cannot completely leave their lairs, they are unable to chase the player and have a limited attack range. They can safely be hit with ranged attacks, but have high health.
