Yuki-Onna

A yuki-onna is a creature of frost that haunts frozen lands and mountains. The male version of this spirit is called Jack Frost. The yuki-onna is a terrifying monster that freezes its victims and is said to summon blizzards to trap humanoids to mercilessly slaughter them. A yuki-onna appears as a very tall humanoid with ice-like skin and breath like frost, usually wearing white.

    Cruel Spirit. An encounter with a yuki-onna is usually fatal, as the fey seems to take sick delight in killing mortals and causing destruction. It isn’t content to wait in its frozen domain and will enter homes using its psychic powers or by slipping inside while in vapor form.

    Mercy Killer. If a yuki-onna discovers a traveler dying in the snows, it may show mercy and give the traveler a quick and painless end. Some stories say a yuki-onna may also take mercy on a creature which invokes it for aid if it is found worthy of the yuki-onna’s mercy.

Shapechanger. The yuki-onna can use its action to polymorph into a cloud of icy vapor or back into its true form. While in vapor form, the yuki-onna can’t take any actions, speak, or manipulate objects. It is weightless, has a flying speed of 30 feet, can hover, and can enter a hostile creature’s space and stop there. In addition, if air can pass through a space, the vapor can do so without squeezing. It has advantage on Strength, Dexterity, and Constitution saving throws, and is immune to nonmagical damage.

Innate Manifestation. The yuki-onna’s innate manifester ability is Charisma (power save DC 16). It can innately manifest the following powers:

At will: accelerated healing (up to 3 power points), extrasensory perception (up to 5 power points), hydrokinesis (up to 5 power points), weather control (up to 1 power point; wind, snow, ice, and fog only)

3/day: ego whip (up to 9 power points), energy blast (up to 9 power points; cold damage only), muddle (up to 5 power points)

Actions

Frost Touch. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 18 (4d6 + 4) cold damage.

Chilling Embrace. Melee Weapon Attack: +7 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the yuki-onna, incapacitated, or restrained. Hit: 11 (2d6 + 4) cold damage. The target’s hit point maximum is reduced by an amount equal to the cold damage taken. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces it hit point maximum to 0.

Frozen Breath (recharge 5-6). Each creature within a 30-foot long line originating from the yuki-onna must make a DC 16 Constitution saving throw. If the save is failed, the creature takes 39 (6d12) cold damage and is frozen in a thin sheet of ice, incapacitating it for 1 minute. The ice can be attacked and has AC 10, 25 hit points, vulnerability to fire and thunder damage, and immunity to cold, necrotic, poison, and psychic damage. If the save is successful the creature only takes half the damage.
