This creature resembles a gigantic centipede covered with chitinous plates of hardened bone that run along its back in double rows. Its rear portion ends in a long, scorpion-like stinger.
Advanced Stegocentipede CR 8
During Combat Although mindless, it does recognize gnolls as allies and won’t attack them-characters disguised as gnolls can move among the immense many-legged vermin safely as long as they don’t attack it. All other creatures are food, and it attacks the closest such target each round.
Morale It fights to the death.
A stegocentipede raises its dorsal spine plates during combat and moves rapidly back and forth. Creatures adjacent to a stegocentipede must succeed on a DC 20 Reflex save each round or take 3d8+4 points of damage from the spine-plates each time they attack whether the attack is successful or not. The save DC is Constitution-based.
Stegocentipedes are rumored among sages to have come to the Material Plane from another plane or dimension, though no proof has been found to support this theory. Whatever their origin, they are greatly feared by adventurers and other dungeon dwelling denizens for their poisonous bite and sting. A typical stegocentipede is 18 feet long. A stegocentipede ranges in color from brown to green.
