REMORHAZ

The remorhaz has ice blue coloration everywhere except along its back where a streak of white sets off the large protrusions there. The creature's multi-faceted eyes are white.

Remorhaz, sometimes known as polar worms, inhabit only the chill wastes. They are very aggressive predators. 

In combat, the remorhaz beats its small wings and rears the front quarter of its body. It then snaps itself forward, striking with blinding speed, and the largest-sized specimens are able to swallow prey whole in this manner.

Prey is swallowed whole on a score of 20. Any victim swallowed in this manner is instantly killed due to the intense heat in the monster's digestive system. 

When aroused, the remorhaz secretes substances internally which cause its intestines to become very hot, and its back protrusions actually glow cherry-red with the excess heat. 

Any non-magical weapon striking the back of a remorhaz will melt from the heat, and any creature touched by these surfaces suffers 10-100 points of damage.

If encountered in its lair, a remorhaz is 25% likely to have a mate and 1-2 eggs there. The size of one of these creatures is determined by its hit dice: a 7 dice remorhaz is 21-ft long, an 8 dice creature 24-ft long, etc. Remorhaz eggs are valued at 5,000 gold pieces each.
