SPECIAL Traits

• Echolocation. The grunthumplema can’t use its blindsight while deafened.
• Freezing Blood. The blood of a grunthumplema freezes anything it touches. If a creature damages the grunthumplema with a melee piercing or slashing weapon, the creature must make a DC 13 Constitution saving throw or take 18 (4d8) cold damage, and be restrained (half damage and not restrained on a successful save). The restrained creature takes 18 (4d8) cold damage at the beginning of its turn and may attempt a saving throw to remove the condition at the end of its turn. If the restrained creature is in frigid water or another environment with extreme cold, they have disadvantage on the saving throw. If the creature fails the saving throw by 5 or more, they are instantly petrified, as their body turns to ice. A restrained creature reduced to 0 hit points from cold damage is instantly petrified.
• Hold Breath. The grunthumplema can hold its breath for 30 minutes.
• Ice Swim. The grunthumplema can swim through nonmagical ice and snow. While doing so, the grunthumplema doesn’t disturb the material it moves through.
• Keen Hearing and Smell. The grunthumplema has advantage on Wisdom (Perception) checks that rely on hearing and smell.

ABOUT

Grunthumplema are an arctic marine variant of chimeras. Ferocious but not evil, they hunt for food and to protect their underwater dens.

Grunthumplema are omnivorous but prefer to eat meat from great beasts. If needed, though, it can adapt to nearly any kind of diet.

Both settled and roaming schools of these creatures exist, and don’t usually interfere with each other. The young are raised in common by all the school’s member.
