Special Abilities

Frostwraith (Ex): The Frostmask can phase through the snow and ice as if it was incorporeal being when it desires. This allows the demon to ignore any hindrance and harm caused by snow, ice, and cold effects that do not explicitly affect incorporeal beings.

Profane Gift Of The Frostmask (Su): Tempter at its heart, the Frostmask can offer power to mortals. Once per day, as a full-round action it may grant profane gift to a willing humanoid by touching the recipient for one round. The target gains +2 profane bonus to an ability score of its choice and resistance to cold 10. A single target can not have more than one profane gift of the Frostmask at a time. As long as the profane gift of the Frostmask persist, the Frostmask can communicate telepathically with the target across any distance, use its greater teleport ability to travel to the target's location, and scry on the bearer as if using greater scrying. A profane gift of the Frostmask can be removed with dispel evil (DC 23). The Frostmask can remove its profane gift as a free action dealing 2d6 points of Charisma drain to the target.

Sense Heat (Ex): The Frostmask can sense presence of sources of heat warmer than the local environment as if using blindsense. It can pinpoint exact position of open fires and all forms of active fire magic as if using blindsight.

Shards Of Ice (Ex): The Frostmask in combat can grow and fire icy shards from its fingers with a range of 60 feet.

The demon know as the Frostmask is a bit of enigma. Cunning, manipulative, cordial, and a bit cowardly, it is a trickster spirit first. It's still a fiend, though, and as a demon it bears affinity for destruction and corruption deep within its (frozen) heart. It seems to be particularly interested in thwarting activities of beings attuned to fire—be they gods, genies, devils or other demons.

In combat it grows scythe-like claws but it prefers to avoid direct combat unless it has advantage over its opponents—available allies or minions, unreachable perch from which it can blast enemies with ice and cold, fighting weaker enemies alone.
