Traits

Ground Disruptor

When the glacier behemoth moves, it can choose to make the area it moves through difficult terrain. When it uses Inexorable Charge, it automatically makes the ground difficult terrain.

Unstoppable

Difficult terrain composed of ice, rocks, sand, or natural vegetation, living or dead, doesn’t cost the glacier behemoth extra movement. Its speed can’t be reduced by any effect.

Actions

Bite

+11 to hit, reach 5 ft (1.5 m). Hit: 4d12+7 piercing damage.

Melee Weapon Attack: +11 to hit, reach 5 ft., one creature. Hit: 33 (4d12 + 7) piercing damage.

Inexorable Charge

If the glacier behemoth moves at least 10 feet, it can then use this action to continue moving in a 40-foot line that is 15 feet wide. Each creature in this line must make a DC 17 Dexterity saving throw. On a failure, a creature takes 35 (10d6) bludgeoning damage and is knocked prone. On a success, a creature takes half the damage and isn't knocked prone. The glacier behemoth's movement along this line doesn't provoke opportunity attacks.

Multiattack

The glacier behemoth makes two bite attacks.
