Although the remorhaz has much in common superficially with lesser vermin, the beast is surprisingly intelligent. While not capable of speech, the typical remorhaz has a good grasp of the Giant tongue, 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.
