The Remorhaz: A RM Conversion

Copyright Kerry Drake © 2004

Edited by Nicholas HM Caldwell for The Guild Companion

"Even a trained beast will attack its master if hungry enough."

Only known to inhabit arctic wastes, the Remorhaz is also called the polar worm. A predator of the highest order, it devours any animal matter including wild animals and humanoids of any size. Known for their aggression, Remorhaz territories are given a wide berth by those are wise.

A remorhaz stands on dozens of chitinous legs. It has a winged head and neck topping a segmented body ice blue in color. Their backs have a streak of white setting off the many protrusions located there.


The remorhaz raises up the front portion of its body by beating its small wings, it then strikes with blinding speed snapping itself forward in an attempt to swallow its prey whole. The remorhaz secretes a substance that causes its intestines to become very hot when aroused, causing its back protrusions to actually glow red from the heat. Any non-magical weapon melts from contact with its back and any creature touched by these surfaces suffers a "C" heat critical.

Remorhaz prefer to burrow into the snow and surface when they hear prey nearby. They are slower than most polar dwellers, so they use this method in an attempt to achieve surprise. The creatures have infravision to 60 feet.


Consisting of a number of rounded smooth tunnels of ice, snow and rock, a remorhazís lair gradually descends to a large central chamber. The remorhaz's hot back repeatedly melts the snow, leaving it to refreeze causing these tunnels to be very slippery. Normally about twice the size of a remorhaz (four times the size for the lair of a mated pair), the central cavern may contain icy stalactites.

They tolerate the presence of other remorhaz in their hunting grounds (a range of nearly 60 miles), except when the game has been hunted to near extinction.


Carnivores, sustained by a diet of deer, elk, and even polar bears, remorhaz mate in late summer and stay together for two months before departing to live solitary existences. Only able to produce offspring three or four times a year, remorhaz nevertheless mate every year. Females lay a clutch of one or two grey-blue eggs and remain with them at all times, coiling around them to keep them warm. Eggs, which are left alone in the freezing cold for even one minute, will never hatch.

Remorhaz live for about 30 years. These creatures can be trained to be excellent guards, causing their eggs to be valued at 500 gold pieces each. A remorhaz can only be trained to obey one or two masters, and even a trained beast will attack its master if hungry enough. The heat secretion of a rhemorhaz, thrym, is valuable as a component for heat-related magical items and can be sold to alchemists for 5-10 gold pieces per flask. A number of flasks equal to the Remorhazís hit points / 10 can be obtained from these monstersí corpses.

A remorhaz is whitish-blue in color but pulses with a reddish glow from the heat its body produces. The creature is a little more than 20 feet long, with a body about 5 feet wide. It weighs about 10,000 pounds.

Remorhazes cannot speak.


Remorhazes hide under the snow and ice until they hear movement above them, then attack from below and surprise prey.

Improved Grab (Ex): To use this ability, a remorhaz must hit an opponent least one size category smaller than itself with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can attempt to swallow the opponent the following round.

Swallow Whole (Ex): When a remorhaz begins its turn with a grappled opponent in its mouth, it can swallow that opponent with a successful grapple check. Once inside, the opponent takes 2d8+12 points of bludgeoning damage plus 8d6 points of fire damage per round from the remorhazís gizzard. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 25 points of damage to the gizzard (AC 15). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. A Huge remorhazís interior can hold 2 Large, 4 Medium, 8 Small, 32 Tiny, 128 Diminutive, or 512 Fine or smaller opponents.

Heat (Ex): An enraged remorhaz generates heat so intense that anything touching its body takes 8d6 points of fire damage. Creatures striking a remorhaz with natural attacks or unarmed attacks are subject to this damage, but creatures striking with melee weapons do not take damage from the remorhazís heat. This heat can melt or char weapons; any weapon that strikes a remorhaz is allowed a DC 18 Fortitude save to avoid destruction. The save DC is Constitution-based. Skills: Remorhazes have a +4 racial bonus on Listen checks.
