Special Traits

  • Freezing Ink. Using special glands, a gelidiceph can release an 80-foot burst of icy-blue ink once every minute as a free action. In moments, the ink freezes into a field of crystalline glacial ice. Any creature within this burst must make a DC 18 Dexterity save, becoming restrained on a failure. A restrained creature may use an action to attempt to break free, with a DC 16 Strength Save. This ice field persists for 10 rounds and is treated as difficult terrain. Heat melts the ice normally.
  • Icy Morphology. A gelidiceph is a massive squid-like elemental with eight arms and two tentacles. Attackers may target each of these limbs separately from the gelidiceph’s main body. Limbs are destroyed once they have taken 20 hit points in damage. Lost limbs regrow after 1d10+10 days.


  • Multiattack. The gelidiceph makes eight slam attacks and one bite attack.
  • Slam. Melee Weapon Attack: +13 to hit, reach 20 ft., one target. Hit: 12 (1d8 + 8) bludgeoning damage and 3 (1d6) cold damage.
  • Bite. Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 18 (3d6 + 8) piercing damage.
  • Grasping Tentacles. As a bonus action, the gelidiceph grapples a single creature within 20 ft. with an Escape Dexterity check of DC 18. If a creature is already grappled, the gelidiceph uses its bonus action to constrict the creature, causing 16 (2d6+8) bludgeoning damage.


Hrinruuk was known for creating fearsome beasts to appease his hunter’s desires. When he sought a challenge tailored for the north, he decided upon a camouflaged creature that would be the perfect predator in ice and snow.

He shaped a massive kraken from the coldest ice, with the heart of a raging water elemental, and the gelidiceph swam off to terrorize all Scarn’s freezing waters, and even its coastal glaciers and snowfields.

With a voracious appetite bestowed by the titanic hunter, the gelidiceph hunts insatiably. Aggressive and mean-spirited, these massive elemental kraken attack and devour any creature they see, dismembering the threats and consuming the prey. It is understandable that few in the civilized settlements of Fenrilik have lived through an encounter with such a titanic threat and returned to tell the tale. A gelidiceph only considers retreat when it has lost 3 or more of its arms, disappearing reluctantly through a huge cloud of freezing ink.
