Special Traits

• Collapsing Colossus. When the bergjotun drops to 0 hit points, it falls over. Any creature on the ground within 30 feet of the bergjotun must make a DC 15 Dexterity saving throw, taking 22 (4d10) bludgeoning damage on a failed save, or half as much damage on a successful one. A creature that fails its save is restrained, blinded, and at risk of suffocating. To lift the corpse, the creature must make a DC 25 Strength saving throw at the end of each of its turns, ending the restrained, blinded, and risk of suffocation conditions on a success.
• Innate Spellcasting. The bergjotun’s innate spellcasting ability is Charisma (spell save DC 17, +10 to hit with spell attacks). It can innately cast the following spells, requiring no material components:
  • At will: meld into stone, move earth, wall of stone
• Legendary Resistance (3/Day). If the bergjotun fails a saving throw, it can choose to succeed instead.
• Magic Resistance. The bergjotun has advantage on saving throws against spells and other magical effects.
• Magic Weapons. The bergjotun’s weapon attacks are magical.
• Siege Monster. The bergjotun deals double damage to objects and structures.
• Stone Camouflage. The bergjotun has advantage on Dexterity (Stealth) checks made to hide in rocky terrain.
• Towering Terror. Any enemy outside the bergjotun that starts its turn within 30 feet of it must succeed on a DC 16 Wisdom saving throw or be frightened until the start of the enemy’s next turn. If the enemy’s saving throw is successful, it is immune to this bergjotun’s Towering Terror for the next 24 hours.

Actions

• Multiattack. The bergjotun makes one melee attack with its whetstone and one with its shield.
• Whetstone. Melee or Ranged Weapon Attack: +17 to hit, reach 15 ft. or 200/800 ft., one target. Hit: 29 (3d12 + 10) bludgeoning damage. If a 1 is rolled on an attack roll with a whetstone, it shatters and can no longer be used.
• Shield Bash. Melee Weapon Attack: +17 to hit, reach 10 ft., one creature. Hit: 29 (3d12 + 10) bludgeoning damage. If the target is a Huge or smaller creature, it must succeed on a DC 25 Strength saving throw or be knocked prone.
• Hurled Stone. Ranged Weapon Attack: +17 to hit, range 200/800 ft., one target. Hit: 43 (6d10 + 10) bludgeoning damage.
• Stomp. The bergjotun stomps one of its feet at a point on the ground within 20 feet of it. Any creature in a 20-foot-radius, 20-foothigh cylinder centered on this point must succeed on a DC 15 Dexterity saving throw or take 33 (6d10) bludgeoning damage and fall prone. Until the bergjotun uses its Stomp again or moves, the creature is restrained. While restrained in this way, the creature (or another creature within 5 feet of it) can use its action to make a DC 25 Strength check. On a success, the creature relocates to an unoccupied space of its choice within 5 feet of the bergjotun and is no longer restrained. Structures, as well as nonmagical objects that are neither being worn nor carried, take the same amount of damage if they are in the cylinder (no save).
• Change Shape. The bergjotun magically polymorphs into a Medium humanoid, or back into its true form. Its statistics are the same in each form. Any equipment the bergjotun is wearing or carrying isn’t transformed. The bergjotun reverts to it true form if it dies.
• Create Mokkurkalfi. The bergjotun can turn any corpse lying on unworked stone within 15 feet into a clay construct known as a mokkurkalfi. The corpse instantly transforms into a mokkurkalfi and acts on the same initiative count as the bergjotun. The mokkurkalfi obeys the bergjotun’s commands and fights until destroyed.

Reactions

• Rock Catching. If a rock or similar object is hurled at the bergjotun, the bergjotun can, with a successful DC 15 Dexterity saving throw, catch the missile and take no bludgeoning damage from it.
