Heated Body. A creature that touches the remorhaz or hits it with a melee attack while within 5 feet of it takes 10 (3d6) fire damage.


Bite. Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 40 (6d10 + 7) piercing damage plus 10 (3d6) fire damage. If the target is a creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and the remorhaz can’t bite another target.

Swallow. The remorhaz makes one bite attack against a Medium or smaller creature it is grappling. If the attack hits, that creature takes the bite’s damage and is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the remorhaz, and it takes 21 (6d6) acid damage at the start of each of the remorhaz’s turns.

If the remorhaz takes 30 damage or more on a single turn from a creature inside it, the remorhaz must succeed on a DC 15 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the remorhaz. If the remorhaz dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 15 feet of movement, exiting prone.

Remorhazes dwell in extensive warrens carved into the hearts of glaciers. The beasts use their heat to melt tunnels through ice, tunnels whose smooth glassy sides swiftly refreeze in their wake to create uncommonly stable and numerous mazes.

Although the remorhaz has much in common superficially with lesser vermin, the beast is surprisingly intelligent. While not capable of speech, the typical remorhaz can learn the rudiments of language if carefully coached, and tribes of giants often use this to their advantage to secure allegiances with the great beasts. Frost giants are particularly obsessed with them, for those giants who brave the cruel and deadly burns a remorhaz can inflict to become “worm friends” gain a potent weapon to use against their enemies—an assassin capable of burrowing up through the floor of a glacial keep to strike directly against a frost giant’s greatest weakness: fire. Other giants use the beasts as living forges, for their backs are hot enough to melt metal.

A remorhaz is 25 feet long and weighs 10,000 pounds.
