    SIZ Note<\/strong><\/p>\n\n\n\n

    Gigantic (SIZ 55). Frost worms occupy a massive space and have a Reach of 25 feet with their Bite and Slam attacks.<\/p>\n\n\n\n

    Cold<\/strong><\/p>\n\n\n\n

    A frost worm’s body radiates supernatural cold. Its Bite and Slam attacks inflict an additional 1d8 Cold damage.<\/p>\n\n\n\n

    Any creature striking a frost worm with an unarmed attack or natural weapon immediately suffers 1d8 Cold damage.<\/p>\n\n\n\n

    Trill<\/strong><\/p>\n\n\n\n

    As a Free Action, the frost worm emits a haunting, resonating trill. All non-frost worms within 100 feet must succeed at a Difficult Stamina check or become Stunned for as long as the worm continues trilling and for 1d4 rounds afterward.<\/p>\n\n\n\n

    A stunned creature that is attacked or shaken violently may immediately attempt another Stamina check.<\/p>\n\n\n\n

    Once a creature successfully resists or recovers from a particular frost worm’s Trill, it is immune to that worm’s Trill for 24 hours.<\/p>\n\n\n\n

    A frost worm cannot use its Breath Weapon while Trilling.<\/p>\n\n\n\n

    Breath Weapon<\/strong><\/p>\n\n\n\n

    Once per hour, a frost worm exhales a 30-foot cone of freezing mist.<\/p>\n\n\n\n

    Creatures within the cone suffer 10d6 Cold damage. A successful Agility (DEX) Save halves the damage.<\/p>\n\n\n\n

    Creatures currently stunned by Trill receive no Save against the Breath Weapon.<\/p>\n\n\n\n

    Death Throes<\/strong><\/p>\n\n\n\n

    When slain, a frost worm explodes into a storm of frozen shards.<\/p>\n\n\n\n

    Every creature within 100 feet suffers 6d6 Cold damage and 8d6 Piercing damage.<\/p>\n\n\n\n

    A successful DEX Save halves both damage types.<\/p>\n\n\n\n

    Darkvision<\/strong><\/p>\n\n\n\n

    A frost worm can see normally in darkness out to 60 feet, provided there is at least the faintest available light.<\/p>\n\n\n\n

    Immunity to Cold<\/p>\n\n\n\n

    A frost worm is completely immune to Cold damage and all magical or mundane effects based on extreme cold.<\/p>\n\n\n\n

    Vulnerability to Fire<\/strong><\/p>\n\n\n\n

    Fire attacks inflict an additional +2d6 Fire damage against a frost worm after all other damage has been calculated.<\/p>\n\n\n\n

    Reagents and Remnants<\/h3>\n\n\n\n

    Frost Worm Heart<\/strong><\/p>\n\n\n\n

    The massive heart of a frost worm radiates supernatural cold for weeks after the creature’s death. Master alchemists prize it for brewing powerful frost oils, cold wards, and enchantments.<\/p>\n\n\n\n

    Value: 1,200 gp<\/p>\n\n\n\n

    Harvesting Difficulty: Very Difficult<\/p>\n\n\n\n

    Icefang Shards<\/strong><\/p>\n\n\n\n

    The worm’s crystalline teeth and jaw fragments remain harder than steel after death. Smiths craft them into masterwork arrowheads, spear tips, and cold-forged blades.<\/p>\n\n\n\n

    Value: 400 gp<\/p>\n\n\n\n

    Harvesting Difficulty: Difficult<\/p>\n\n\n\n

    Frostscale Hide<\/strong><\/p>\n\n\n\n

    The worm’s thick, frost-infused hide can be crafted into exceptional armor that protects against extreme cold and harsh environments.<\/p>\n\n\n\n

    Value: 900 gp<\/p>\n\n\n\n
