Shapechanger. The spökvatten can use its action to magically polymorph into a Large cloud of mist, into a beast or humanoid of challenge rating 2 or lower, or back into its true form (that of a Medium fey). Anything it is carrying or wearing transforms with it. It reverts to its true form if it dies.

While in beast or humanoid form, the spökvatten retains its game statistics and ability to speak, but its AC, movement modes, Strength, Dexterity, and special senses are replaced by those of the new form, and it gains any statistics and capabilities (except class features, legendary actions, and lair actions) that the new form has but that it lacks.

In mist form, the spökvatten can only use its icy fog ability, and it is unable to speak or manipulate objects. It is weightless, has a flying speed of 20 feet, can hover, and can enter a hostile creature’s space and stop there. In addition, if air can pass through a space, the mist can do so without squeezing, and it can’t pass through water. It has advantage on Strength, Dexterity, and Constitution saving throws, and it is immune to all nonmagical damage.

Actions

Cold Touch. Melee Spell Attack: +7 to hit, reach 5 ft., one target. Hit: 26 (4d10 + 4) cold damage. The target must succeed on a DC 15 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Icy Fog (Recharge 5–6). The spökvatten exhales a cloud of freezing mist in a 15-foot cone. Each creature in that area must make a DC 15 Dexterity saving throw, taking 36 (8d8) cold damage on a failed save, or half as much damage on a successful one.
