A winged and clawed humanoid monster around 3 feet tall with genderless, hairless bodies and blue skin so light as to be almost white

An Ice Devil is a winged and clawed humanoid monster around 3 feet tall. Its hairless bodies are genderless, with blue skin so light as to be almost white.

Found most commonly on the cold layers of Stygia and Cania, ice devils serve as commanders of the infernal armies of the Nine Hells, tormenting lesser devils as an outlet for their anger and resentment. Coveting the power of their pit fiend superiors, ice devils work ceaselessly toward promotion, slaughtering the enemies of the Nine Hells and claiming as many souls as they can for their archdevil masters.

Resembling a giant bipedal insect, an ice devil has clawed hands and feet, powerful mandibles, and a long tail covered in razor-sharp spikes. Some carry barbed spears whose icy touch can render a foe all but helpless in combat.

Variant: Ice Devil Spear

Some ice devils have the following action options.

Multiattack

The devil makes two attacks: one with its spear and one with its tail.

Ice Spear

mw +10 to hit, reach 10 ft., one target. (2d8 + 5) piercing damage + 10 (3d6) cold damage. If the target is a creature, it must succeed on a 15 Constitution saving throw, or for 1 minute, its speed is reduced by 10 feet; it can take either an action or a bonus action on each of its turns, not both; and it can't take reactions. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Ice Devil

Devil of Antipathy and Intellectual Arrogance

Heartless strategists of the Nine Hells, ice devils—also known as gelugons—forsake emotion to indulge in their own malicious interpretations of logic. For them, the multiverse is a puzzle that must be solved to benefit them, their masters, and the Nine Hells.

Ice devils act maliciously, disguising their whims as reason and strategy. In the service of evil masters, these insectile devils patiently plot the movements of infernal armies and scheme ways to fulfill wicked goals. They might also serve as guardians, owing to their martial prowess and ability to reshape battlefields with walls of ice.

When indulging their own schemes, ice devils tempt mortals to forsake empathy and social connections to embrace selfish, destructive visions of intellectualism. After isolating victims, these devils drain them of their secrets or send them forth to spread fractious dogmas cloaked as reason.

Ice devils usually lurk in frozen realms, particularly the frigid layer of Cania in the Nine Hells.

Part of the charm of ice devils is that they always think they're smarter than you. Mmm—there are few pleasures sweeter than proving a devil wrong.

Upright remorhaz-like devils with humanoid limbs and barbed tails that dominate the frozen 8th plane of Hell

Ice devils resemble upright remorhaz with humanoid arms and legs, and knotted, barbed tails. They dominate the 8th plane of Hell, which serves as their frozen home. They are also very strong (18.76 strength) and enjoy torturing their victims before killing them. Ice devils also have secret personal names which can be used to summon them, if the name is somehow known to the conjurer. In combat, these devils will usually rely on their claws, mandibles, and tails. Occasionally (25%), they wield long, magical spears which they can use to impale and freeze their victims (2d6 damage plus the victim must save vs paralysation or be reduced to half their normal move).
